[0072] Embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present disclosure, and are not to be construed as limitations of the present disclosure. On the contrary, the embodiments of the present disclosure include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0073] The present disclosure is described in detail below with reference to specific embodiments.

[0074] Figure 1 A schematic diagram of the structure of an electronic device provided by an embodiment of the present disclosure.

[0075] like Figure 1 As shown, the electronic device includes: a power module, an interface module, a first charging module, a second charging module, a first switch module and a second switch module; wherein,

[0076] The interface module is respectively connected to the first end of the first switch module and the first end of the second charging module, the second end of the second charging module is connected to the first end of the second switch module, the second end of the second switch module is respectively connected to the second end of the first switch module and the first end of the first charging module, and the second end of the first charging module and the third end of the second charging module are respectively connected to the power supply module.

[0077] According to some embodiments, the interface module is used to connect to an external power source to receive a first voltage input by the external power source.

[0078] According to some embodiments, both the first charging module and the second charging module may be used to perform voltage conversion on the first voltage, so that the converted first voltage can charge the power module.

[0079] In some embodiments, the branch where the first charging module is located can be, for example, a main charging path, and the branch where the second charging module is located can be, for example, an auxiliary charging path. The second charging module has a higher efficiency under large current conditions, so the charging power is larger, that is, the maximum charging power of the first charging module is less than the maximum charging power of the second charging module.

[0080] For example, the charging power range of the first charging module may be 7.5W to 18W, and the charging power of the second charging module may be greater than 27W.

[0081] According to some embodiments, the power module may include, for example, a battery, the second end of the first charging module and the third end of the second charging module are respectively connected to the positive electrode of the battery, and the negative electrode of the battery is grounded.

[0082] Optionally, in one embodiment of the present disclosure, when the interface module is connected to the external power supply and the first switch module is in the disconnected state, the current input by the external power supply can sequentially pass through the interface module, the first end of the second charging module, the second charging module, and the third end of the second charging module to charge the power module; and,

[0083] The current input by the external power supply can sequentially pass through the interface module, the first end of the second charging module, the second charging module, the second end of the second charging module, the second switch module, and the first charging module to charge the power module.

[0084] According to some embodiments, when charging the power module through an external power supply, first, the interface module can transmit the first voltage input by the external power supply to the second charging module. Then, the second charging module can convert the first voltage into a second voltage and a third voltage. Secondly, the second switch module is controlled to be in an on state so that the second voltage is input to the first end of the first charging module through the second switch module; at the same time, the first switch module is controlled to be in an off state, which can prevent the current output by the interface module from being fed back to the second end of the second charging module through the first switch module. Finally, the first charging module can convert the input second voltage into a fourth voltage, and both the third voltage and the fourth voltage can be used to charge the power module. Therefore, the first charging module and the second charging module can charge the power module at the same time, which can increase the charging speed of the electronic device.

[0085] In some embodiments, the second voltage refers to the voltage output by the second end of the second charging module, that is, the voltage input by the second charging module to the first charging module.

[0086] In some embodiments, the third voltage refers to a voltage output by a third terminal of the second charging module.

[0087] According to some embodiments, the voltage value corresponding to the first voltage is greater than the voltage value corresponding to the second voltage, the voltage value corresponding to the second voltage is greater than the voltage value corresponding to the third voltage, and the voltage value corresponding to the third voltage is the same as the voltage value corresponding to the fourth voltage.

[0088] For example, the voltage value corresponding to the first voltage may be 20, the voltage value corresponding to the second voltage may be 10, and the voltage values ​​corresponding to the third voltage and the fourth voltage may both be 5.

[0089] Optionally, in one embodiment of the present disclosure, when the interface module is connected to the device to be charged, the first switch module and the second switch module can be controlled to be in an off state, so as to control the current output by the power module to pass through the third end of the second charging module, the second charging module, the first end of the second charging module, and the interface module in sequence to reversely charge the device to be charged. Therefore, the convenience of using the electronic device can be improved.

[0090] Optionally, in one embodiment of the present disclosure, the interface module includes at least one of the following interface sub-modules:

[0091] Wired interface submodule;

[0092] Wireless interface submodule.

[0093] For example, the interface module may include only a wired interface submodule, such as Figure 2 The interface module may also include only a wireless interface submodule, such as Figure 3 The interface module may also include a wired interface submodule and a wireless interface submodule, such as Figure 4 shown.

[0094] For example, the interface module may further include other interface submodules that can be used to connect to an external power source in addition to the wired interface submodule and the wireless interface submodule.

[0095] According to some embodiments, the wired interface submodule refers to a module used for establishing a wired connection with an external device, such as an external power supply. Figure 5 This is a schematic diagram of the structure of an electronic device provided by an embodiment of the present disclosure. Figure 5 As shown, the wired interface submodule includes a wired interface terminal and a third switch module; wherein,

[0096] The wired interface terminal is connected to a first end of the third switch module, and a second end of the third switch module is respectively connected to a first end of the first switch module and a first end of the second charging module.

[0097] It should be noted that Figure 5 FIG. 2 shows the specific structure of the wired interface submodule when the interface module includes both the wired interface submodule and the wireless interface submodule. Figure 5 In the case where the interface module other than the wireless interface module includes a wired interface submodule, the specific structure of the wired interface submodule is the same as Figure 5 As shown, no further repetition is given.

[0098] In some embodiments, the wired interface terminal is used to establish a wired connection with an external device, such as an external power source and a wired device to be charged.

[0099] In some embodiments, when the wired interface terminal is connected to an external device, the third switch module may be controlled to be in a conducting state, so that the wired interface submodule is in a conducting state.

[0100] In some embodiments, the wired interface terminal can be, for example, a Universal Serial Bus (USB) interface. During the wired forward charging process, a wired connection is made between the USB interface and the external power supply, and a first voltage input by the external power supply can be received through the power supply (VBUS) pin of the USB interface, and the first voltage is transmitted to the third switch module. During the wired reverse charging process, a wired connection is made between the USB interface and the wired device to be charged, so that the current output by the power module can be controlled to pass through the third end of the second charging module, the second charging module, the first end of the second charging module, the third switch module and the USB interface in sequence to perform wired reverse charging for the device to be charged. Therefore, the convenience of using the electronic device can be improved.

[0101] According to some embodiments, the wireless interface submodule refers to a module for wirelessly connecting to an external device, such as an external power source. Figure 5 As shown, the wireless interface submodule includes a wireless interface terminal and a fourth switch module; wherein,

[0102] The wireless interface terminal is connected to the first end of the fourth switch module, and the second end of the fourth switch module is respectively connected to the first end of the first switch module and the first end of the second charging module.

[0103] It should be noted that Figure 5 The specific structure of the wireless interface submodule is shown when the interface module includes both the wired interface submodule and the wireless interface submodule. Figure 5 In the case where the interface module other than the wireless interface module includes a wireless interface submodule, the specific structure of the wireless interface submodule is the same as Figure 5 As shown, no further repetition is given.

[0104] According to some embodiments, the wireless interface terminal is used to wirelessly connect to an external device, including but not limited to an external power source and a wireless device to be charged.

[0105] In some embodiments, the wireless interface terminal can be, for example, a wireless charging chip. During the wireless forward charging process, the wireless charging chip is wirelessly connected to the external power supply, and the wireless charging chip acts as a receiving (receive, Rx) terminal, which can convert the AC signal input by the external power supply into a DC signal and output it to the fourth switch module for forward charging. During the wireless reverse charging process, the wireless charging chip is wirelessly connected to the wireless device to be charged, and the wireless charging chip can act as a transmitting (Transmit, Tx) terminal to convert the DC signal into an AC signal and output it to the wireless device to be charged for wireless charging.

[0106] In some embodiments, when the wireless interface terminal is connected to an external power source, the fourth switch module may be controlled to be in an on state, so that the wireless interface submodule is in an on state.

[0107] It should be noted that when the interface module includes both a wired interface submodule and a wireless interface submodule, when only the wired interface terminal is connected to an external power source, the third switch module can be controlled to be in an on state and the fourth switch module can be controlled to be in an off state to prevent the current input from the external power source from being fed back to the wireless interface terminal through the third switch module and the fourth switch module in sequence. Similarly, when only the wireless interface terminal is connected to an external power source, the fourth switch module can be controlled to be in an on state and the third switch module can be controlled to be in an off state to prevent the current input from the external power source from being fed back to the wired interface terminal through the fourth switch module and the third switch module in sequence. Therefore, the safety of the electronic device when in use can be improved.

[0108] According to some embodiments, Figure 5 As shown, the electronic device may further include a protection switch module; wherein,

[0109] The first end of the protection switch module is respectively connected to the wireless interface terminal and the first end of the fourth switch module, and the second end of the protection switch module is respectively connected to the second end of the first switch module, the first end of the first charging module and the second end of the second switch module.

[0110] It should be noted that, in the case where the interface module includes a wireless interface sub-module, a protection switch module can be provided to support the wireless interface sub-module to realize the wireless reverse charging function. Figure 5 Only the configuration of the protection switch module is shown when the interface module includes both the wired interface submodule and the wireless interface submodule. Figure 5 For the case where the interface modules other than the wireless interface module include the wireless interface submodule, the setting of the protection switch module is the same as Figure 5 As shown, no further repetition is given.

[0111] According to some embodiments, the protection switch module refers to a switch module with a protection function. When the voltage input to the protection switch module is lower than the protection voltage threshold, the protection switch module will be in an on state; on the contrary, when the voltage input to the protection switch module is not lower than the protection voltage threshold, the protection switch module will be in an off state. Therefore, the safety of the electronic device when in use can be improved.

[0112] In some embodiments, the protection switch module may be an overvoltage protection (OVP) switch or an OVP chip. The protection voltage threshold does not specifically refer to a fixed threshold, and the protection voltage threshold may be adjusted according to actual application scenarios.

[0113] In some embodiments, when the wired interface terminal is connected to an external power source and the wireless interface terminal is connected to a wireless device to be charged, by controlling the first switch module to be in a closed state, the second switch module to be in a conductive state, the third switch module to be in a conductive state, and the fourth switch module to be in a disconnected state, the second voltage output by the second end of the second charging module can be input to the wireless interface terminal through the protection switch module, so that the wireless interface terminal can wirelessly charge the wireless device to be charged. Therefore, the convenience of using the electronic device can be improved.

[0114] It should be noted that the second voltage output by the second end of the second charging module matches the working voltage of the wireless interface terminal, and the working voltage of the wired interface terminal is greater than the working voltage of the wireless interface terminal. For example, the working voltage of the wired interface terminal may be 20V, and the working voltage and the second voltage of the wireless interface terminal may both be 10V.

[0115] Optionally, in an embodiment of the present disclosure, the switch modules provided in the embodiment of the present disclosure include but are not limited to the first switch module, the second switch module, the third switch module and the fourth switch module, and their on and off states can be controlled by at least one of the following modules in the electronic device:

Therefore, the charging module can be reused to control the on-off state of the switch module, and there is no need to set up a control module or a driving module separately, which can reduce the cost of the electronic device.

[0120] It should be noted that the driving end of the second charging module includes a first sub-driving end and a second sub-driving end, that is, the control end of the second switch module can be connected to at least one of the first sub-driving end and the second sub-driving end of the second charging module.

[0125] According to some embodiments, a back-to-back transistor switch circuit refers to a circuit formed by connecting two transistors back-to-back. The back-to-back transistor switch circuit can prevent voltage backflow and improve the safety of electronic equipment when in use.

[0126] In some embodiments, the back-to-back transistor switch circuit includes a first transistor, a second transistor, a first diode, and a second diode; wherein,

[0127] The connection point between the source of the first transistor and the anode of the first diode is the first end of the back-to-back transistor switch circuit, the drain of the first transistor is respectively connected to the drain of the second transistor, the cathode of the first diode and the cathode of the second diode, the connection point between the source of the second transistor and the anode of the second diode is the second end of the back-to-back transistor switch circuit, and the connection point between the gate of the first transistor and the gate of the second transistor is the control end of the back-to-back transistor switch circuit.

[0128] In some embodiments, when a driving signal received at a control terminal of the back-to-back transistor switch circuit can drive the first transistor and the second transistor to be in a conducting state, the back-to-back transistor switch circuit is in a conducting state.

[0129] For example, when the first transistor and the second transistor are both N-type metal oxide semiconductor field effect transistors (MOSFET, MOS), the gate of the first transistor and the gate of the second transistor can be in the on state when receiving a high-level driving signal; when the first transistor and the second transistor are both PMOS, the gate of the first transistor and the gate of the second transistor can be in the on state when receiving a low-level driving signal.

[0130] According to some embodiments, a single-transistor switch circuit refers to a switch circuit that uses only one transistor as a switch.

[0132] The connection point between the drain of the third transistor and the cathode of the third diode is the first end of the single transistor switch circuit, the connection point between the source of the third transistor and the anode of the third diode is the second end of the single transistor switch circuit, and the gate of the third transistor is the control end of the single transistor switch circuit.

[0133] In some embodiments, when the driving signal received at the control terminal of the single-transistor switch circuit can drive the third transistor to be in the on state, the single-transistor switch circuit can be in the on state.

[0134] For example, when the third transistor is an NMOS, the gate of the third transistor can be turned on by receiving a high-level driving signal; when the third transistor is a PMOS, the gate of the third transistor can be turned on by receiving a low-level driving signal.

[0139] A driving end of at least one charge pump circuit is connected to a control end of the second switch module.

[0140] According to some embodiments, the driving end of any charge pump circuit includes a first sub-driving end and a second sub-driving end, and the control end of the second switch module can be connected to at least one of the first sub-driving end and the second sub-driving end of any charge pump circuit. The first sub-driving end of any charge pump circuit can be connected to the control end of the third switch module, and the second sub-driving end of any charge pump circuit can be connected to the control end of the fourth switch module.

[0141] In some embodiments, Figure 6 As shown, the second charging module includes two charge pump circuits, namely a first charge pump circuit and a second charge pump circuit; wherein the first sub-driving end of the first charge pump circuit is respectively connected to the control end of the second switch module and the control end of the third switch module, and the second sub-driving end of the first charge pump circuit is respectively connected to the control end of the second switch module and the control end of the fourth switch module.

[0142] It should be noted that when only one charge pump circuit is used for charging, the charging power can be 90 W. When two charge pump circuits are used for charging at the same time, the charging power can be 120 W.

[0143] According to some embodiments, a charge pump circuit includes a charge pump chip (CP); wherein,

[0144] The OVPGATE end of the charge pump chip is the first sub-driving end of the charge pump circuit, the WPCGATE end of the charge pump chip is the second sub-driving end of the charge pump circuit, the first end of the charge pump chip is the first end of the charge pump circuit, the second end of the charge pump chip is the second end of the charge pump circuit, and the third end of the charge pump chip is the third end of the charge pump circuit;

[0145] The ratio of the port voltage corresponding to the first end of the charge pump chip to the port voltage corresponding to the second end of the charge pump chip and the port voltage corresponding to the third end of the charge pump chip is 4:2:1.

[0146] For example, when the input voltage received by the first end of the charge pump chip, that is, the first voltage is 20V, the second voltage output by the second end of the charge pump chip may be 10V, and the third voltage output by the third end of the charge pump chip may be 5V.

[0148] The connection point between the drain of the first transistor module Q1 and the drain of the second transistor module Q2 is the first end of the charge pump chip, the source of the first transistor module Q1 is respectively connected to the drain of the fourth transistor module Q4 and the first end of the first capacitor C1, the source of the second transistor module Q2 is respectively connected to the drain of the third transistor module Q3 and the first end of the second capacitor C2, and the connection point between the source of the third transistor module Q3, the source of the fourth transistor module Q4, the drain of the fifth transistor module Q5, the drain of the sixth transistor module Q6 and the first end of the fifth capacitor C5 is the second end of the charge pump chip;

[0149] The source of the fifth transistor module Q5 is respectively connected to the drain of the seventh transistor module Q7, the drain of the tenth transistor module Q10 and the first end of the third capacitor C3, the source of the seventh transistor module Q7 is respectively connected to the drain of the eighth transistor module Q8 and the second end of the first capacitor C1, the second end of the third capacitor C3 is respectively connected to the source of the ninth transistor module Q9, the source of the eleventh transistor module Q11 and the drain of the twelfth transistor module Q12, the drain of the eleventh transistor module Q11 is respectively connected to the drain of the sixteenth transistor module Q16 and the first end of the sixth capacitor C6;

[0150] The source of the sixth transistor module Q6 is respectively connected to the drain of the thirteenth transistor module Q13, the drain of the eighteenth transistor module Q18 and the first end of the fourth capacitor C4, the source of the eighteenth transistor module Q18 is respectively connected to the drain of the seventeenth transistor module Q17 and the second end of the second capacitor C2, the second end of the fourth capacitor C4 is respectively connected to the source of the fourteenth transistor module Q14, the source of the sixteenth transistor module Q16 and the drain of the fifteenth transistor module Q15, the connection point between the source of the tenth transistor module Q10, the drain of the ninth transistor module Q9, the source of the thirteenth transistor module Q13 and the drain of the fourteenth transistor module Q14 is the third end of the charge pump chip;

[0151] The source of the eighth transistor module Q8 , the source of the twelfth transistor module Q12 , the source of the fifteenth transistor module Q15 , the source of the seventeenth transistor module Q17 , the second end of the fifth capacitor C5 , and the second end of the sixth capacitor C6 are grounded.

[0152] In some embodiments, Figure 7 As shown, the charge pump chip also integrates a seventh capacitor C7 and an eighth capacitor C8; wherein,

[0153] A connection point between a first end of the seventh capacitor C7 and the drain of the first transistor module Q1 and the drain of the second transistor module Q2 is an input end of the charge pump chip, and a second end of the seventh capacitor C7 is grounded;

[0154] The connection point between the first end of the eighth capacitor C8 and the source of the tenth transistor module Q10, the drain of the ninth transistor module Q9, the source of the thirteenth transistor module Q13 and the drain of the fourteenth transistor module Q14 is the second output end of the charge pump chip, and the second end of the eighth capacitor C8 is grounded.

[0155] In some embodiments, a pre-charging operation may be performed before the charge pump chip enters the working state, and the first capacitor C1, the second capacitor C2, the third capacitor C3, and the fourth capacitor C4 are charged according to the first voltage until the capacitor voltage corresponding to the first capacitor C1 and the capacitor voltage corresponding to the second capacitor C2 are both the second voltage, and the capacitor voltage corresponding to the third capacitor C3 and the capacitor voltage corresponding to the fourth capacitor C4 are both the third voltage. Then, the charge pump chip will enter the working state, that is, alternately switch between the first conduction state and the second conduction state, so that the second end outputs the second voltage and the third end outputs the third voltage.

[0156] In some embodiments, when the charge pump chip switches from the pre-charging state to the working state, the charge pump chip first enters the first conduction state, at which time, the first transistor module Q1 is in the conduction state, the second transistor module Q2 is in the disconnection state, the third transistor module Q3 is in the conduction state, the fourth transistor module Q4 is in the disconnection state, the fifth transistor module Q5 is in the conduction state, the sixth transistor module Q6 is in the disconnection state, the seventh transistor module Q7 is in the conduction state, the eighth transistor module Q8 is in the disconnection state, the ninth transistor module Q9 is in the conduction state, the tenth transistor module Q10 is in the disconnection state, the eleventh transistor module Q11 is in the conduction state, the twelfth transistor module 12 is in the disconnection state, the thirteenth transistor module Q13 is in the conduction state, the fourteenth transistor module Q14 is in the disconnection state, the fifteenth transistor module Q15 is in the conduction state, the sixteenth transistor module Q16 is in the disconnection state, the seventeenth transistor module Q17 is in the conduction state, and the eighteenth transistor module Q18 is in the disconnection state.

[0157] In this case, there will be the following three paths inside the charge pump chip:

[0158] In the first path, the current flows sequentially through the first end of the charge pump chip, the first transistor module Q1, the first capacitor C1, the seventh transistor module Q7, the third capacitor C3, the ninth transistor module Q9, the third end of the charge pump chip, and the ground.

[0159] In the second path, the current flows sequentially through the first end of the charge pump chip, the first transistor module Q1, the first capacitor C1, the seventh transistor module Q7, the third capacitor C3, the eleventh transistor module Q11, the sixth capacitor C6, and the ground.

[0160] In the third path, the current flows sequentially through the first end of the charge pump chip, the first transistor module Q1, the first capacitor C1, the seventh transistor module Q7, the fifth transistor module Q5, the fifth capacitor C5, and the ground.

[0161] It should be noted that, since the ratio between the port voltage corresponding to the first end of the charge pump chip and the port voltage corresponding to the second end and the port voltage corresponding to the third end of the charge pump chip is 4:2:1, that is, the first voltage is twice the second voltage and four times the third voltage. Therefore, the capacitance values ​​of the first capacitor C1, the second capacitor C2, and the fifth capacitor C5 are all the same, and are all twice the capacitance values ​​of the third capacitor C3, the fourth capacitor C4, and the sixth capacitor C6, so that the fifth capacitor C5 can be charged to the second voltage.

[0162] For example, when the first voltage is 20V and the capacitor voltage of the second capacitor C2 is 10V, the fifth capacitor C5 can be charged to 20V-10V=10V.

[0163] Next, the charge pump chip is converted from the first conduction state to the second conduction state. At this time, the first transistor module Q1 is in the off state, the second transistor module Q2 is in the on state, the third transistor module Q3 is in the off state, the fourth transistor module Q4 is in the on state, the fifth transistor module Q5 is in the off state, the sixth transistor module Q6 is in the on state, the seventh transistor module Q7 is in the off state, the eighth transistor module Q8 is in the on state, the ninth transistor module Q9 is in the off state, the tenth transistor module Q10 is in the on state, the eleventh transistor module Q11 is in the off state, the twelfth transistor module Q12 is in the on state, the thirteenth transistor module Q13 is in the off state, the fourteenth transistor module Q14 is in the on state, the fifteenth transistor module Q15 is in the off state, the sixteenth transistor module Q16 is in the on state, the seventeenth transistor module Q17 is in the off state, and the eighteenth transistor module Q18 is in the on state.

[0164] In this case, there will be the following three paths inside the charge pump chip:

[0165] In the first path, the current flows sequentially through the first terminal of the charge pump chip, the second transistor module Q2, the second capacitor C2, the eighteenth transistor module Q18, the fourth capacitor C4, the fourteenth transistor module Q14, the third terminal of the charge pump chip, and the ground.

[0166] In the second path, the current flows sequentially through the first end of the charge pump chip, the second transistor module Q2, the second capacitor C2, the eighteenth transistor module Q18, the fourth capacitor C4, the sixteenth transistor module Q16, the sixth capacitor C6, and the ground.

[0167] In the third path, the current flows sequentially through the first end of the charge pump chip, the second transistor module Q2, the second capacitor C2, the eighteenth transistor module Q18, the sixth transistor module Q6, the fifth capacitor C5, and the ground.

[0168] At this time, since the fifth capacitor C5 has been charged to the second voltage, the above three paths can all remain in the on state. Then, the charge pump chip switches alternately between the first on state and the second on state, and the fifth capacitor C5 can maintain a constant voltage output of the second voltage.

[0169] According to some embodiments, Figure 4 As shown, the transistor modules in the charge pump chip, namely the first transistor module Q1 to the eighteenth transistor module Q18, can each include an NMOS and a body diode; wherein,

[0170] The connection point between the drain of the NMOS and the cathode of the body diode is the drain of the transistor module, the connection point between the source of the NMOS and the anode of the body diode is the source of the transistor module, and the gate of the NMOS is the gate of the transistor module.

[0171] It should be noted that Figure 7 Only the circuit between the first end, the second end and the third end of the charge pump chip is shown, and the circuit corresponding to the OVPGATE end and the WPCGATE end of the charge pump chip is not limited. The OVPGATE end and the WPCGATE end can output high-level or low-level driving signals.

[0172] Optionally, in one embodiment of the present disclosure, the first charging module may include a charging chip (power management integrated circuit, PMIC). The control end of the first switch module may be connected to a USB_DRV pin of the PMIC. The USB_DRV pin is similar to the OVPGATE end and the WPCGATE end of the charge pump chip, and may output a drive signal to the third transistor to control the on / off state of the third transistor.

[0173] Optionally, in one embodiment of the present disclosure, Figure 6 As shown, the electronic device further includes a system circuit, and the system voltage supply terminal VSYS of the first charging module is connected to the system circuit. At this time, when the interface module is not connected to an external power source, the second terminal of the first charging module will serve as an input terminal to receive the fifth voltage input from the positive electrode of the battery, so that the first charging module can convert the fifth voltage into a system power supply voltage, and power the system circuit through the system voltage supply terminal VSYS.

[0174] In summary, the electronic device provided by the embodiment of the present disclosure can improve the charging speed of the electronic device by setting a first switch module and a second switch module and controlling the on and off states of the first switch module and the second switch module, so that the first charging module and the second charging module can be charged at the same time as the power module.
