Description

Technical Field

[0001] The present application relates to the technical field of power management, and in particular to an electronic device. Background Art

[0002] Electronic devices are generally set with a shutdown voltage. When the source voltage provided by the battery in the electronic device is lower than the shutdown voltage, the electronic device will automatically shut down. Among them, the shutdown voltage can generally be set to 3.2V. However, when the source voltage provided by the battery is lower than 3.2V, there is still some power in the battery that has not been used, so the battery power is not fully released when the electronic device is shut down. How to use this part of the power to extend the battery life of the electronic device is an urgent problem to be solved in this field. Utility Model Content

[0003] The present application provides an electronic device for extending the battery life of the electronic device.

[0004] In a first aspect, an embodiment of the present application provides an electronic device, which may include: a battery, multiple RF analog modules, a first boost circuit and a controller, wherein the first boost circuit is respectively connected to the battery, each RF analog module and the controller, and the controller is also connected to the battery; the controller is used to: in response to a source voltage provided by the battery being less than a first reference voltage, control the first boost circuit to boost the source voltage to at least the first reference voltage, and output the first reference voltage to at least one first RF analog module; in response to the source voltage being not less than the first reference voltage, control the first boost circuit to output the source voltage to at least one first RF analog module; wherein the first RF analog module is the RF analog module currently in operation, and when there is one first RF analog module, the first reference voltage is not less than the first minimum operating voltage of the first RF analog module; when there are multiple first RF analog modules, the first reference voltage is not less than the minimum value in the intersection of the operating voltage intervals of each first RF analog module. In this way, even if the source voltage provided by the battery is low and less than the first reference voltage, the first boost circuit can still provide a suitable voltage to each first RF analog module by boosting the source voltage to ensure that each first RF analog module can work, thereby reducing the shutdown voltage of the electronic device and extending the battery life of the electronic device. In addition, all RF analog modules can share the same first boost circuit, which can reduce the number of first boost circuits and reduce the manufacturing cost of the electronic device.

[0005] Optionally, the electronic device may also include a SoC (System on Chip), which is connected to the controller, and the SoC is used to: determine the first RF analog module and the first reference voltage and inform the controller. In other words, the SoC can determine which one or which of the first RF analog modules are the first RF analog modules, and can also determine the first reference voltage corresponding to the first RF analog module. At this time, the SoC can send the identifier of the first RF analog module and the first reference voltage to the controller in the form of instructions, messages or other forms of signals to inform the controller, so that the controller can determine the first RF analog module and the first reference voltage, and thus can control the first boost circuit based on this.

[0006] Of course, the controller can be pre-installed with the corresponding working voltage ranges and identifiers of each RF analog module. At this time, the SoC can send the identifier of the first RF analog module to the controller, and the controller can find the corresponding working voltage range from the built-in correspondence based on the acquired identifier, and then determine the first reference voltage, thereby realizing control of the first boost circuit.

[0007] Since all RF analog modules do not work at the same time, the current allowed to pass through the first boost circuit is: the maximum value of the rated current of each RF analog module, so that a suitable current can be provided to the first RF analog module, further ensuring that the connected first RF analog module can work.

[0008] Each RF analog module may include but is not limited to: a power amplifier for transmitting satellite signals (i.e., a satellite power amplifier, abbreviated as satellite PA), and a power amplifier for transmitting cellular network signals (i.e., a cellular network power amplifier), and the cellular network power amplifier may include: a power amplifier for transmitting 2G mobile network signals (i.e., a 2G mobile network power amplifier, abbreviated as 2G PA), a power amplifier for transmitting 3G mobile network signals (i.e., a 3G mobile network power amplifier, abbreviated as 3G PA), a power amplifier for transmitting 4G mobile network signals (i.e., a 4G mobile network power amplifier, abbreviated as 4G PA), a power amplifier for transmitting 5G mobile network signals (i.e., a 5G mobile network power amplifier, abbreviated as 5G PA), and other RF analog modules. When the RF analog module is any one of 3G PA, 4G PA and 5G PA, APT (Auto Power Tracking) or ET (Envelope Tracking) may be further arranged between the first boost circuit and these RF analog modules. The voltage provided by the first boost circuit is first output to the APT or ET, and then transmitted to these RF analog modules after power amplification by the APT or ET, so as to meet the signal strength requirements emitted by these RF analog modules and ensure the normal use of electronic equipment in 3G, 4G or 5G scenarios.

[0009] Optionally, the output power of the first boost circuit can be dynamically adjusted according to the needs of different working conditions to avoid power waste, thereby reducing the power consumption of the electronic device. For example, when the satellite PA is in working state and the cellular network power amplifier is not currently in working state, the output power of the first boost circuit can be set to be no less than the rated power of the satellite PA, so that the satellite PA can work normally, thereby providing an effective satellite signal to the electronic device. Alternatively, when the 2G PA is currently in working state and the 3G PA, 4G PA, 5G PA and satellite PA are not currently in working state, the output power of the first boost circuit can be set to be no less than the rated power of the 2G PA, so that the 2G PA can work normally, thereby providing an effective 2G mobile network signal to the electronic device, and ensuring the normal reception and call of the electronic device. Alternatively, when the 4G PA and the 5G PA are currently in working order, and the 2G PA, the 3G PA, and the satellite PA are currently not in working order, the output power of the first boost circuit can be set to: not less than the sum of the rated powers of the 4G PA and the 5G PA, so as to ensure that the 4G PA and the 5G PA can work normally, thereby providing the electronic device with effective 4G mobile network signals and 5G mobile network signals, and ensuring that the electronic device can use the mobile network normally.

[0010] In addition, the output power range of the first boost circuit can be pre-configured, and the output power range can meet the power requirements of various working conditions; at this time, the actual output power of the first boost circuit can be automatically adjusted according to the power required by the current working conditions; or, the rated power of the RF analog module currently in operation can be obtained by the SoC and informed to the controller, and then the controller controls the actual output power of the first boost circuit based on various working conditions.

[0011] Among them, if there are multiple first RF analog modules, it means that there are multiple RF analog modules currently in working state; and the number of first RF analog modules may be different or the same in different working conditions. At this time, the sum of the rated powers of the first RF analog modules in each working condition can be determined, so that each working condition corresponds to a sum of rated powers, and then when the sums of rated powers corresponding to each working condition are sorted, the maximum sum of rated powers can be obtained (and referred to as the first value). If the sum of the rated powers of all RF analog modules is called the second value, the output power range of the first boost circuit can be set to: not less than the first value and not greater than the second value, so that the output power of the first boost circuit can meet the power requirements of various working conditions and ensure the normal use of electronic equipment.

[0012] Optionally, the electronic device may further include: a first power management unit and a second power management unit, the second minimum operating voltage of the first power management unit is less than the third minimum operating voltage of the second power management unit, and the first power management unit is connected to the battery; the electronic device may further include a second boost circuit, the second boost circuit is respectively connected to the battery, the second power management unit and the controller; the controller is also used to: in response to the source voltage provided by the battery being less than the third minimum operating voltage, control the second boost circuit to boost the source voltage to at least the third minimum operating voltage, and output the third minimum voltage to the second power management unit; in response to the source voltage being not less than the third minimum operating voltage, control the second boost circuit to output the source voltage to the second power management unit. Wherein, the first power management unit is a device that supports low voltage operation, so the second minimum operating voltage of the first power management unit can be lower, and when the second minimum operating voltage is lower than the shutdown voltage of the electronic device, and the voltage provided by the battery is lower than the shutdown voltage, the first power management unit can still work. The second power management unit is a device that does not support low voltage operation, so the third minimum operating voltage of the second power management unit will be higher than the second minimum operating voltage, such as but not limited to the third minimum operating voltage being equal to the shutdown voltage. At this time, by setting up a second boost circuit, even if the source voltage provided by the battery is small and lower than the third minimum operating voltage, the second boost circuit can still provide the second power management unit with a voltage not less than the third minimum operating voltage through the boost processing of the source voltage, so as to meet the normal operation of the second power management unit that does not support low-voltage operation, and can also reduce the shutdown voltage of the electronic device and extend the battery life of the electronic device.

[0013] The second boost circuit may be, but is not limited to, a Boost circuit.

[0014] Furthermore, there are multiple second power management units and at least one boost circuit; there is one boost circuit, and the second boost circuit is connected to each second power management unit, that is, multiple second power management units are connected to the second boost circuit, so that the voltage processed by the second boost circuit can be transmitted to each second power management unit respectively, which can not only make full use of the battery power and ensure the normal operation of each second power management unit, but also simplify the structure of the electronic device and reduce the manufacturing cost. There are multiple second boost circuits, each of which is connected to at least one second power management unit. In this case, each second boost circuit can be connected to one or more second power management units, and different second boost circuits can be connected to different second power management units; further, the second boost circuit is set in a one-to-one correspondence with the second power management unit, so that each second boost circuit can provide an accurate voltage to the corresponding second power management unit to meet the working requirements of the second power management unit and improve the flexibility of the design.

[0015] Further, when each second boost circuit is connected to at least two second power management units, the controller is specifically used to: in response to the source voltage being less than the second reference voltage, control the second boost circuit to boost the source voltage to at least the second reference voltage, and output the second reference voltage to the corresponding at least two second power management units; in response to the source voltage being not less than the second reference voltage, control the second boost circuit to output the source voltage to the corresponding at least two second power management units; wherein, when the operating voltage intervals of each second power management unit in the at least two second power management units have an intersection, the second reference voltage is not less than the minimum value in the intersection. Thus, the second boost circuit can provide appropriate voltages to each correspondingly connected second power management unit to ensure that each connected second power management unit can work.

[0016] Of course, among the multiple second power management units, there may be two or more second power management units whose operating voltage intervals do not overlap. In this case, the second power management units whose operating voltage intervals overlap are divided into one category, and the second power management units whose operating voltage intervals do not overlap are divided into different categories. The same category of second power management units corresponds to the same second boost circuit, and different categories of second power management units correspond to different second boost circuits. In this way, voltage can be provided to different categories of second power management units through different second boost circuits to ensure that each category of second power management units can obtain a suitable voltage. It can also avoid providing too high a voltage to the second power management unit, which is beneficial to reducing the power consumption of electronic equipment.

[0017] Since the second power management units connected to the second boost circuit may work at the same time, the current allowed to pass through the second boost circuit is: the sum of the rated currents of the corresponding second power management units, so as to provide appropriate current to the corresponding second power management units, further ensuring that the connected second power management units can work.

[0018] Optionally, the electronic device may further include a power conversion chip, the power conversion chip may include a voltage regulating unit, the electronic device may further include a switch, the voltage regulating unit is respectively connected to the charging interface of the electronic device, the first end of the switch, and the controller, the second end of the switch is connected to the battery, and the control end of the switch is connected to the controller; the controller is also used to: in response to charging the battery, control the switch to close, and control the voltage regulating unit to process the charging voltage input through the charging interface, and output the processed charging voltage to the battery, thereby realizing battery charging.

[0019] Among them, the second boost circuit can be arranged outside the power conversion chip, or the second boost circuit can be arranged inside the power conversion chip, and the second boost circuit has a structure different from the voltage regulating unit, or the voltage regulating unit is also connected to the second power management unit, and the voltage regulating unit is the second boost circuit, that is, the voltage regulating unit is multiplexed as the second boost circuit.

[0020] The voltage regulating unit may include: a voltage regulating circuit and a step-down circuit. When the voltage regulating unit is multiplexed as a second step-up circuit, the voltage regulating circuit is respectively connected to the charging interface, the controller, the step-down circuit and the battery, and the step-down circuit is also respectively connected to the charging interface, the controller, the first end of the switch and the second power management unit, the first end of the switch is also connected to the second power management unit, and the control end of the switch is connected to the controller; the controller is used to: in response to the source voltage being less than the third minimum operating voltage, control the switch to be disconnected, and control the voltage regulating circuit to perform voltage multiplication processing on the source voltage and output it to the step-down circuit, and control the step-down circuit to step down the voltage output by the voltage regulating circuit and output it to the second power management unit; wherein, the voltage output to the second power management unit is at least the third minimum operating voltage; in response to the source voltage being not less than the third minimum operating voltage, control the switch to be closed, and output the source voltage to the second power management unit. In this way, even if the source voltage provided by the battery is small and less than the third minimum operating voltage, the voltage regulating unit can still provide the second power management unit with a voltage not less than the third minimum operating voltage through the boost processing of the source voltage to meet the normal operation of the second power management unit, and can also reduce the shutdown voltage of the electronic device and extend the battery life of the electronic device. In addition, by implementing the function of the second boost circuit through the voltage regulating unit, the original structure in the electronic device can be reused to extend the battery life of the electronic device without adding additional structures, thereby reducing the manufacturing cost of the electronic device.

[0021] The voltage regulating circuit may be, but is not limited to, a switched capacitor, and the step-down circuit may be, but is not limited to, a BUCK circuit. When the switched capacitor is used in the forward direction, the voltage can be stepped down, and when used in the reverse direction, the voltage can be multiplied. In addition, the switch may be disposed inside the power conversion chip, or may be disposed outside the power conversion chip, depending on the actual situation. Similarly, the controller may be disposed outside the power conversion chip, or may be disposed inside the power conversion chip, depending on the actual situation.

[0022] Each second power management unit is connected to a corresponding device, and each first power management unit is also connected to a corresponding device. A device can be connected to multiple first power management units, so that when one of the first power management units connected to the device cannot work effectively, the other connected first power management units can provide a suitable voltage to ensure the normal operation of the device. And the first power management units connected to different devices can be the same, which can reduce the number of first power management units, simplify the structure of the electronic device, and reduce the manufacturing cost. Optionally, the first power management unit and the second power management unit can be, but are not limited to: Buck Boost circuit, PMU (Power Management Unit, power management module) chip or a power amplifier (i.e., smart PA) with a PMU chip embedded. The device connected to the first power management unit and the device connected to the second power management unit can be determined according to actual conditions and are not limited here.

[0023] Optionally, the battery can be a silicon negative electrode lithium battery, wherein the silicon negative electrode battery can include: a positive electrode, a negative electrode, a diaphragm and an electrolyte, the positive electrode and the negative electrode are isolated by the diaphragm, and the positive electrode, the diaphragm and the negative electrode are stacked or wound to form a battery cell, and the battery cell is immersed in the electrolyte to form a silicon negative electrode battery. The negative electrode made of silicon material can be called a silicon negative electrode. Since silicon material has a higher theoretical specific capacity (such as 4200mAh / g) and a higher lithium insertion potential than metallic lithium, it can effectively reduce the risk of metallic lithium precipitation, thereby effectively improving the safety performance of silicon negative electrode lithium batteries. For the materials for making the positive electrode, diaphragm and electrolyte, any material that can realize the functions of the positive electrode, diaphragm and electrolyte known to those skilled in the art can be used, and is not limited here.

[0029] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings.

[0030] It should be noted that the same reference numerals in the drawings of this application represent the same or similar structures, and thus their repeated description will be omitted. The words expressing positions and directions described in this application are all explained using the drawings as examples, but they can be changed as needed, and the changes are included in the protection scope of this application. The drawings of this application are only used to illustrate the relative position relationship and do not represent the true proportion.

[0031] In order to facilitate understanding of the technical solution provided by the embodiments of the present application, its application scenario is first described below.

[0032] The electronic device provided in the embodiments of the present application may include various terminal devices with built-in rechargeable batteries, wherein the terminal devices may include but are not limited to smart phones, smart TVs, smart TV set-top boxes, smart watches, personal computers (PCs), wearable devices, smart broadband and other devices, which are not listed one by one here.

[0033] Figure 1 The schematic diagram of the structure of the electronic device is shown as an example. Figure 1 As shown, the electronic device includes: a charging interface 10, a battery 20, a power conversion chip 30, and a radio frequency analog module 40. The power conversion chip 30 includes: a voltage regulating unit 31, a switch k0 and a controller 32. The voltage regulating unit 31 includes: a switch capacitor 31a and a BUCK circuit 31b. The controller 32 is connected to the charging interface 10, the switch capacitor 31a, the BUCK circuit 31b, the battery 20 and the switch k0 respectively. Figure 1 The connection relationship between the switch k0 and the controller 32 is not shown, the switch capacitor 31a is also connected to the battery 20 and the charging interface 10, the BUCK circuit 31b is also connected to the charging interface 10, the first end of the switch k0 and the RF analog module 40, and the second end of the switch k0 is connected to the battery 20. When the charger m1 is connected to the charging interface 10 and the external power supply m2 respectively, the charger m1 processes the power provided by the external power supply m2 and outputs it to the charging interface 10, thereby charging the battery 20 in the electronic device.

[0034] The specific charging process may include: the controller 32 determines the type of the charger m1 connected to the charging interface 10. If the determined type is the original type, the controller 32 controls the switch capacitor 31a to step down the charging voltage input from the charging interface 10 and output it to the battery 20 to charge the battery 20; when the battery 20 is charged to the preset voltage, the controller 32 controls the switch capacitor 31a to stop working, controls the switch k0 to close, and controls the BUCK circuit 31b to continue stepping down the charging voltage input from the charging interface 10 and outputting it to the battery 20 to charge the battery 20 until the battery 20 is fully charged. Among them, the preset voltage can be set according to actual conditions, for example, but not limited to the preset voltage is the voltage corresponding to the battery 20 at a certain SOC (for example, but not limited to 60% SOC, 70% SOC or 80% SOC, etc.). If the determined type is not the original type, the controller 32 controls the switch k0 to close, and controls the BUCK circuit 31b to step down the charging voltage input from the charging interface 10 and output it to the battery 20 to charge the battery 20 until the battery 20 is fully charged. When the battery 20 is discharging, the controller 32 controls the switch k0 to close, so that the battery 20 is connected to the RF analog module 40, so that the source voltage provided by the battery 20 can be output to the RF analog module 40, and the battery 20 will not be controlled by the BUCK circuit 31b and the switch capacitor 31a in the power conversion chip 30 when discharging.

[0035] However, electronic devices are generally set with a shutdown voltage, and when the source voltage provided by the battery 20 in the electronic device is lower than the shutdown voltage, the electronic device will automatically shut down. Among them, the shutdown voltage can generally be set to 3.2 V. However, when the source voltage provided by the battery 20 is lower than 3.2 V, some of the power in the battery 20 has not been used, so the power of the battery 20 is not completely released when the electronic device is shut down.

[0036] Based on this, an embodiment of the present application provides an electronic device for utilizing the unreleased power in the battery 20 to extend the battery life of the electronic device.

[0037] The electronic device is explained and illustrated below in conjunction with specific embodiments.

[0038] Figure 2 The structural diagram of the electronic device provided by the present application is exemplarily shown. Figure 2As shown, the electronic device includes: a battery 20, multiple RF analog modules 40, a first boost circuit 51 and a controller 32. The first boost circuit 51 is respectively connected to the battery 20, each RF analog module 40, and the controller 32, and the controller 32 is also connected to the battery 20; all RF analog modules 40 will not work at the same time, that is, only some RF analog modules 40 are working at the same time, for example: assuming that there are three RF analog modules 40 in total, only one RF analog module 40 may be working at the same time, or there may be two RF analog modules 40 working at the same time; of course, the number of RF analog modules 40 is not limited to three, and three are just taken as an example for illustration here. For the convenience of description, in the embodiments of the present application, the RF analog module 40 currently in operation is referred to as the first RF analog module. If there is only one first RF analog module, then if the source voltage is less than the first minimum operating voltage of the first RF analog module, the controller 32 controls the first boost circuit 51 to boost the source voltage to at least the first minimum operating voltage and then output it to the first RF analog module; if the source voltage is not less than the first minimum operating voltage of the first RF analog module, the controller 32 controls the first boost circuit 51 to output the source voltage to the first RF analog module. If there are multiple first RF analog modules, the intersection of the operating voltage intervals of the first RF analog modules can be determined, and the minimum value (hereinafter referred to as the minimum value) can be found from the intersection. At this time, if the source voltage is less than the minimum value, the controller 32 can control the first boost circuit 51 to boost the source voltage to at least the minimum value and then output it to each first RF analog module; if the source voltage is not less than the minimum value, the controller 32 can control the first boost circuit 51 to output the source voltage to each first RF analog module. In this way, even if the source voltage provided by the battery 20 is low and less than the first minimum operating voltage or the minimum value, the first boost circuit 51 can still provide a suitable voltage to each first RF analog module through the boost processing of the source voltage to ensure that each first RF analog module can work, thereby reducing the shutdown voltage of the electronic device and extending the battery life of the electronic device. In addition, all RF analog modules 40 can share the same first boost circuit 51, which can reduce the number of first boost circuits 51 and reduce the production cost of the electronic device.

[0039] The electronic device also includes: SoC60 and a first power management unit 71, SoC60 is connected to the first power management unit 71 and the controller 32 respectively, the first power management unit 71 can provide a driving voltage for SoC60 so that SoC60 can work normally; and, SoC60 can determine which one or which of the first RF analog modules 40 are the first RF analog modules, and can also determine the first minimum operating voltage or minimum value of the first RF analog module. At this time, SoC60 can send the identification of the first RF analog module and the first minimum operating voltage (or minimum value) to the controller 32 in the form of instructions, messages or other forms of signals to inform the controller 32, so that the controller 32 can determine the first RF analog module and the first minimum operating voltage (or minimum value), so as to control the first boost circuit 51 based on this.

[0040] Of course, the controller 32 may have pre-built-in corresponding working voltage ranges and identifications of each RF analog module 40. In this case, the SoC 60 may send the identification of the first RF analog module to the controller 32. The controller 32 may then find the corresponding working voltage range from the built-in corresponding relationship based on the acquired identification, and then determine the first minimum working voltage or minimum value, thereby realizing control over the first boost circuit 51.

[0041] In addition, since all RF analog modules 40 do not work at the same time, the current allowed to pass by the first boost circuit 51 is: the maximum value of the rated current of each RF analog module 40, so that a suitable current can be provided to the first RF analog module, further ensuring that the connected first RF analog module can work.

[0042] Optionally, each RF simulation module 40 may include but is not limited to: a power amplifier for transmitting satellite signals (i.e., a satellite power amplifier, abbreviated as satellite PA), and a power amplifier for transmitting cellular network signals (i.e., a cellular network power amplifier), and the cellular network power amplifier may include: a power amplifier for transmitting 2G mobile network signals (i.e., a 2G mobile network power amplifier, abbreviated as 2G PA), a power amplifier for transmitting 3G mobile network signals (i.e., a 3G mobile network power amplifier, abbreviated as 3G PA), a power amplifier for transmitting 4G mobile network signals (i.e., a 4G mobile network power amplifier, abbreviated as 4G PA), a power amplifier for transmitting 5G mobile network signals (i.e., a 5G mobile network power amplifier, abbreviated as 5G PA), and other RF simulation modules 40. When the RF simulation module 40 is any one of 3G PA, 4G PA and 5GPA, APT or ET can also be arranged between the first boost circuit 51 and these RF simulation modules 40. The voltage provided by the first boost circuit 51 is first output to the APT or ET, and then transmitted to these RF simulation modules 40 after power amplification by the APT or ET, so as to meet the signal strength requirements emitted by these RF simulation modules 40 and ensure the normal use of electronic equipment in 3G, 4G or 5G scenarios.

[0043] Wherein, when the satellite PA is in working state and the cellular network power amplifier is not in working state, the output power of the first boost circuit 51 can be set to be not less than the rated power of the satellite PA, so that the satellite PA can work normally, thereby providing effective satellite signals for the electronic device. Alternatively, when the 2G PA is in working state and the 3G PA, 4G PA, 5G PA and satellite PA are not in working state, the output power of the first boost circuit 51 can be set to be not less than the rated power of the 2G PA, so that the 2G PA can work normally, thereby providing effective 2G mobile network signals for the electronic device, and ensuring the normal call reception of the electronic device. Alternatively, when the 4G PA and the 5G PA are both in working state and the 2G PA, 3G PA and satellite PA are not in working state, the output power of the first boost circuit 51 can be set to be not less than the sum of the rated powers of the 4G PA and the 5G PA, so that the 4G PA and the 5G PA can work normally, thereby providing effective 4G mobile network signals and 5G mobile network signals for the electronic device, and ensuring that the electronic device can use the mobile network normally.

[0044] In addition, the output power range of the first boost circuit 51 can be pre-configured, and the output power range can meet the power requirements of various working conditions; at this time, the actual output power of the first boost circuit 51 can be automatically adjusted according to the power required by the current working conditions; or, the rated power of the RF analog module 40 currently in working state can be obtained by SoC60 and informed to the controller 32, and then the controller 32 controls the actual output power of the first boost circuit 51 based on various working conditions.

[0045] If there are multiple first RF analog modules, it means that there are multiple RF analog modules 40 currently in operation; and the number of first RF analog modules may be different or the same in different working conditions. At this time, the sum of the rated powers of the first RF analog modules in each working condition can be determined, so that each working condition corresponds to a sum of rated powers. When the sums of the rated powers corresponding to each working condition are sorted, the maximum sum of rated powers (referred to as the first value) can be obtained. If the sum of the rated powers of all RF analog modules 40 is called the second value, the output power range of the first boost circuit 51 can be set to: not less than the first value and not greater than the second value, so that the output power of the first boost circuit 51 can meet the power requirements of various working conditions and ensure the normal use of electronic equipment.

[0046] Figure 3 The structural diagram of the electronic device provided by the present application is exemplarily shown. Figure 3 As shown, the structure of the electronic device in this embodiment is similar to the above Figure 2 The structures of the electronic devices described in the embodiments shown are basically similar, except that: Figure 2 On the basis of the structure of the electronic device introduced in the illustrated embodiment, the electronic device further includes: a power conversion chip 30 and a second boost circuit 52 , and the second boost circuit 52 is arranged outside the power conversion chip 30 .

[0047] Optionally, the electronic device may further include: a second power management unit 72. The first power management unit 71 is a device that supports low-voltage operation, so the second minimum operating voltage of the first power management unit 71 may be lower, for example, the second minimum operating voltage is lower than the shutdown voltage of the electronic device, so that when the voltage provided by the battery 20 is lower than the shutdown voltage, the first power management unit 71 can still work. The second power management unit 72 is a device that does not support low-voltage operation, so the third minimum operating voltage of the second power management unit 72 will be higher than the second minimum operating voltage, for example but not limited to the third minimum operating voltage being equal to the shutdown voltage, so that when the voltage provided by the battery 20 is lower than the shutdown voltage, the second power management unit 72 cannot work. Based on this, the electronic device may further include a second boost circuit 52, the battery 20 is connected to the first power management unit 71, and the second boost circuit 52 is connected to the battery 20, the second power management unit 72 and the controller 32 respectively; at this time, in response to the source voltage provided by the battery 20 being less than the third minimum working voltage, the controller 32 controls the second boost circuit 52 to boost the source voltage to at least the third minimum working voltage and then output it to the second power management unit 72; in response to the source voltage being not less than the third minimum working voltage, the controller 32 controls the second boost circuit 52 to output the source voltage to the second power management unit 72. In this way, even if the source voltage provided by the battery 20 is small and less than the third minimum working voltage, the second boost circuit 52 can still provide the second power management unit 72 with a voltage not less than the third minimum working voltage through the boost processing of the source voltage to meet the normal operation of the second power management unit 72, and can also reduce the shutdown voltage of the electronic device and extend the battery life of the electronic device.

[0048] The second boost circuit 52 may be, but is not limited to, a Boost circuit.

[0049] Furthermore, a second boost circuit 52 may be provided, and in this case, a plurality of second power management units 72 are all connected to the second boost circuit 52, so that the voltage processed by the second boost circuit 52 can be transmitted to each second power management unit 72 respectively. This can not only make full use of the electric energy of the battery 20 and ensure the normal operation of each second power management unit 72, but also simplify the structure of the electronic device and reduce the production cost.

[0050] Alternatively, multiple second boost circuits 52 may be provided (not shown in the figure), in which case each second boost circuit 52 may be connected to one or more second power management units 72, and different second boost circuits 52 may be connected to different second power management units 72; further, the second boost circuits 52 and the second power management units 72 are provided in a one-to-one correspondence, so that each second boost circuit 52 can provide an accurate voltage to the corresponding second power management unit 72 to meet the working requirements of the second power management unit 72, thereby improving the flexibility of the design.

[0051] Further, when the second boost circuit 52 is connected to at least two second power management units 72, when the operating voltage intervals of each second power management unit 72 in the plurality of second power management units 72 connected to the same second boost circuit 52 have an intersection, the second reference voltage can be set to be not less than the minimum value in the intersection. At this time, if the source voltage is less than the second reference voltage, the controller 32 can control the second boost circuit 52 to boost the source voltage to at least the second reference voltage and then output it to the corresponding at least two second power management units 72; if the source voltage is not less than the second reference voltage, the controller 32 can control the second boost circuit 52 to output the source voltage to the corresponding at least two second power management units 72; thereby, the second boost circuit 52 can provide a suitable voltage to each correspondingly connected second power management unit 72 to ensure that each connected second power management unit 72 can work. Furthermore, since the second power management units 72 connected to the second boost circuit 52 may operate simultaneously, the current allowed to pass through the second boost circuit 52 is: the sum of the rated currents of the correspondingly connected second power management units 72, so as to provide appropriate current to the corresponding second power management units 72, further ensuring that the connected second power management units 72 can operate.

[0052] Of course, among the multiple second power management units 72, there may be two or more second power management units 72 whose operating voltage intervals do not intersect. Taking two second power management units 72 whose operating voltage intervals do not intersect as an example, if the two second power management units 72 are respectively marked as A1 and A2, two second boost circuits 52 can be set, where one second boost circuit 52 is connected to A1 and the other second boost circuit 52 is connected to A2. In this way, voltage can be provided to the two second power management units 72 through different second boost circuits 52 to ensure that the two second power management units 72 can obtain a suitable voltage. It can also avoid providing too high a voltage to the second power management unit 72, which is beneficial to reducing the power consumption of the electronic device.

[0053] The electronic device may further include a power conversion chip 30, which may include: a voltage regulating unit 31 and a switch k0, wherein the voltage regulating unit 31 is respectively connected to the charging interface 10 of the electronic device, the first end of the switch k0, and the controller 32, the second end of the switch k0 is connected to the battery 20, and the control end of the switch k0 is connected to the controller 32 ( Figure 3 (not shown); at this time, the controller 32 is also used for: when charging the battery 20, controlling the switch k0 to close, and controlling the voltage regulating circuit to process the charging voltage input through the charging interface 10 and output it to the battery 20, thereby realizing charging of the battery 20. Among them, the second boost circuit 52 can be arranged outside the power conversion chip 30, and the switch k0 can be arranged outside the power conversion chip 30 in addition to being arranged inside the power conversion chip 30, and the specific details can be determined according to the actual situation. Similarly, the controller 32 can be arranged outside the power conversion chip 30, and can also be arranged inside the power conversion chip 30, and the specific details can be determined according to the actual situation. In addition, the specific structure and function implementation principle of the voltage regulating unit 31 are the same as those described above. Figure 1 The implementation principle of the intermediate voltage regulating unit 31 is similar, and the details can be found in the above Figure 1 The switch k0 may be a switch k0 device having a control function, such as a transistor, a relay or a contactor.

[0054] Each second power management unit 72 is connected to a corresponding device, and each first power management unit 71 is also connected to a corresponding device. A device can be connected to multiple first power management units 71, so that when one of the first power management units 71 connected to the device cannot work effectively, the other connected first power management units 71 can provide a suitable voltage to ensure the normal operation of the device. And the first power management units 71 connected to different devices can be the same, which can reduce the number of first power management units 71, simplify the structure of the electronic device, and reduce the manufacturing cost. Optionally, the first power management unit 71 and the second power management unit 72 can be, but are not limited to: Buck Boost circuit, PMU chip or power amplifier (i.e. smart PA) with a PMU chip embedded.

For the PMU chip connected to the screen, the PMU chip can be used to provide a suitable voltage to the screen to achieve the normal operation of the screen. For the PMU chip connected to the short-range chip, the PMU chip can be used to provide a suitable voltage to the short-range chip to achieve the normal operation of the short-range chip, wherein the short-range chip may include but is not limited to at least one of a WIFI chip, a Bluetooth chip and a GPS chip. For the PMU chip connected to OTG (USB On-The-On, USB data connection module), the PMU chip can be used to provide a suitable voltage to OTG to achieve the normal operation of OTG. For the PMU chip connected to the motor driver chip, the PMU chip can be used to provide a suitable voltage to the motor driver chip to achieve the normal operation of the motor driver chip. It should be understood that the PMU chip connected to NFC, the PMU chip connected to the screen, the PMU chip connected to the short-range chip, the PMU chip connected to OTG, and the PMU chip connected to the motor drive chip all belong to the second power management unit 72 .

[0056] For the Buck Boost connected to the touch screen, the Buck Boost can be used to provide a suitable voltage to the touch screen to achieve normal operation of the touch screen. For the Buck Boost and PMU chips connected to the camera, any one of the Buck Boost and PMU chips can be used to provide a suitable voltage to the camera to achieve normal operation of the camera. For the two PMU chips connected to the SoC or UFS (Universal Flash Strorage) system, any one of the two PMU chips can be used to provide a suitable voltage to the SoC or UFS system to achieve normal operation of the SoC or UFS system. For the smart PA connected to the loudspeaker, the smart PA can be used to provide a suitable voltage to the loudspeaker to achieve normal operation of the loudspeaker. The RF device includes an RF digital module and an RF analog module. For the PMU chip connected to the RF digital module, the PMU chip can be used to provide a suitable voltage to the RF digital module to achieve normal operation of the RF digital module. It should be understood that the Buck Boost connected to the touch screen, the PMU chip connected to the camera, the PMU chip connected to the SoC or UFS system, the smart PA connected to the loudspeaker, and the PMU chip connected to the RF digital module all belong to the first power management unit 71.

[0057] It is worth noting that in Figure 3 In order to avoid making the structure of the accompanying drawings too complicated, the connection relationship between the SoC and the controller 32 is not shown in this figure, but this does not mean that there is no connection relationship between the two, it is just not shown here.

[0058] It should be understood that the structure of the electronic device in this embodiment is similar to the above Figure 2 The similarities between the structures of the electronic devices described in the embodiments shown can be found in the above Figure 2 The related introduction in the illustrated embodiment will not be repeated any more.

[0059] Figure 5 The structural diagram of the electronic device provided by the present application is exemplarily shown. Figure 5 As shown, the structure of the electronic device in this embodiment is similar to the above Figure 3 The structures of the electronic devices described in the illustrated embodiments are basically similar, except that the voltage regulating unit 31 in the power conversion chip 30 is multiplexed as the second boost circuit 52 .

[0060] Optionally, the power conversion chip 30 includes a voltage regulating unit 31, and the voltage regulating unit 31 includes: a voltage regulating circuit 311 and a buck circuit 312, the voltage regulating circuit 311 is respectively connected to the charging interface 10, the controller 32, the buck circuit 312 and the battery 20, the buck circuit 312 is also respectively connected to the charging interface 10, the controller 32, the first end of the switch k0 and the second power management unit 72, the first end of the switch k0 is also connected to the second power management unit 72, and the control end of the switch k0 is connected to the controller 32 ( Figure 5(not shown). Wherein, when the source voltage is less than the third minimum working voltage, the controller 32 can control the switch k0 to be disconnected, cut off the path between the battery 20 and the second power management unit 72, and control the voltage regulating circuit 311 to perform voltage doubling processing on the source voltage and output it to the step-down circuit 312, and control the step-down circuit 312 to step down the voltage output by the voltage regulating circuit 311 and output it to the second power management unit 72, wherein the voltage output to the second power management unit 72 is at least the third minimum working voltage; when the source voltage is not less than the third minimum working voltage, the controller 32 can control the switch k0 to be closed, so that the battery 20 is connected to the second power management unit 72, so that the source voltage can be output to the second power management unit 72. In this way, even if the source voltage provided by the battery 20 is small and less than the third minimum working voltage, the voltage regulating unit 31 can still provide a voltage not less than the third minimum working voltage to the second power management unit 72 through the step-up processing of the source voltage to meet the normal operation of the second power management unit 72, and can also reduce the shutdown voltage of the electronic device and extend the battery life of the electronic device. In addition, by implementing the function of the second boost circuit 52 through the voltage regulating unit 31, the original structure in the electronic device can be reused to extend the battery life of the electronic device without adding additional structures, thereby reducing the manufacturing cost of the electronic device.

[0061] The voltage regulating circuit 311 is a switched capacitor, and the step-down circuit 312 is a BUCK circuit. When the switched capacitor is used in the forward direction, the voltage can be stepped down, and when used in the reverse direction, the voltage can be multiplied. It should be understood that the BUCK circuit and the switched capacitor include multiple transistors, some of which can be connected to the controller 32, and the controller 32 can control the conduction and disconnection of the corresponding transistors, thereby realizing the control of the BUCK circuit and the switched capacitor.
