[0026] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0027] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which this application belongs.

[0028] DrMOS (Driver-MOSFET) is a power management chip used for CPU core power management in laptops. It is a step-down converter responsible for converting high voltage to low voltage to power the CPU.

[0029] In the current Intel latest platform MTL design, MTL refers to Memory Traffic Limiter, which is a technology used to adjust the memory access speed. The CPU power supply requires 7 DrMOS to work independently, and each one is an independent working mode. Figure 1 As shown, each DrMOS chip 100 performs independent voltage regulation tasks, so they are independent of each other in layout, and each is equipped with a corresponding input capacitor 200 to ensure smooth and stable current supply. However, as the number of DrMOS chips 100 increases, the limited space resources of the motherboard face greater pressure.

[0030] In view of the above technical problems, the present application provides a power management module, which aims to effectively save space in the motherboard of an electronic device by reducing the number of capacitor components. This optimized power solution is not only applicable to laptop computers, but also widely applicable to a variety of electronic devices such as desktop computer motherboards and server motherboards to meet the growing demand for device integration and space utilization efficiency.

[0031] like Figure 2 As shown, an embodiment of the present application provides a power management module, including: multiple voltage regulation modules 1, the voltage regulation module 1 is used to adjust the voltage output by the power supply, the voltage regulation module 1 includes a target port 101; an energy storage unit 2, the power supply end of the energy storage unit 2 is connected to the target ports 101 of the multiple voltage regulation modules 1; the target port 101 is used to receive the power supply signal of the energy storage unit 2.

[0032] The number of voltage regulating modules 1 can be set to multiple according to actual application requirements. The voltage regulating module 1 can be a combination of discrete MOSFET and driver IC, integrated power chip, intelligent power module, DrMOS chip, etc. Each voltage regulating module 1 can have an independent voltage regulation function, which can adjust the input power supply voltage to the stable working voltage required by a specific device or system.

[0033] The energy storage unit 2 can be a battery, a capacitor, an inductor, etc., which can store and release electrical energy. The energy storage unit 2 can manage the charging of the energy storage unit 2 when the power is normally supplied, and control the energy storage unit 2 to supply power to the target port 101 of the voltage regulation module 1 when the power is interrupted, so as to achieve the continuity and stability of the output voltage. As an electrical storage element, the energy storage unit 2 can be a single entity or a collection of multiple similar or different elements (such as a battery pack, a capacitor array, etc.). Through integration and management, a larger energy storage capacity and higher power output can be achieved.

[0034] The power management module provided in the embodiment of the present application can realize the sharing of energy storage resources by connecting the power supply end of an energy storage unit 2 to the target ports 101 of multiple voltage regulation modules 1, thereby reducing the number of energy storage units 2 and significantly improving space utilization.

[0035] In some embodiments, the voltage regulation module 1 may be a DrMOS chip, and the energy storage unit 2 may be an input capacitor.

[0036] The power management module can use a DrMOS chip as a voltage regulation module 1. This integrated solution significantly reduces the size and complexity of the module, and reduces the number of external components and wiring length. The energy storage unit 2 can use an input capacitor, which simplifies the overall structure of the power management module and does not require additional batteries or large-capacity energy storage devices, thereby reducing weight and costs. The input capacitor can be used as an energy storage unit 2, which can quickly release or absorb charges when the power supply voltage changes transiently or the load changes suddenly, effectively assisting the DrMOS chip to maintain the stability of the output voltage and achieve the reliability and response speed of the power supply system.

[0037] The power management module provided in the embodiment of the present application adopts a DrMOS chip as the voltage regulation module 1 and uses an input capacitor as the energy storage unit 2, thereby achieving miniaturization, simplified design, low cost and excellent voltage stability performance of the module.

[0038] In some embodiments, the target port 101 of the voltage regulating module 1 is located at a target side 102 of the voltage regulating module 1 , and a side where a plurality of voltage regulating modules 1 are adjacent to each other is the target side 102 .

[0039] Multiple voltage regulating modules 1 (such as DrMOS chips, etc.) can be arranged adjacent to each other to form a compact array structure, which effectively saves space. The adjacent side of the voltage regulating modules 1 can be the "target side 102", and the target port 101 of the voltage regulating module 1 can be located on this side. So that the target ports 101 of adjacent voltage regulating modules 1 are arranged opposite to each other, that is, facing each other, a centralized and orderly input area can be formed, making the structure of the entire power management module more compact, which is conducive to improving space utilization. By connecting the power supply end of the energy storage unit 2 to the target port 101 located on the target side 102, the wiring structure of the energy storage unit 2 and the voltage regulating module 1 can be simplified, reducing the length and complexity of the connection.

[0040] The target side 102 of the voltage regulation module 1 in different forms is exemplified below. Figure 3 As shown, for example:

[0041] In some embodiments, in a rectangular voltage regulation module 1, the target side 102 can be a longer side of the voltage regulation module 1, so that when multiple voltage regulation modules 1 are arranged adjacent to each other, their target ports 101 can be arranged along a straight line facing each other to form a neat input / output channel, which can maximize the use of planar space and facilitate the centralized arrangement of the connection harnesses of the energy storage unit 2 in the same direction to reduce crossing and confusion.

[0042] In some embodiments, in a circular voltage regulating module 1, its target side 102 can be set to a fixed interval or arc segment on the circumference, and can be set to a 1 / 4 or 1 / 6 sector of its circumference. When multiple voltage regulating modules 1 are arranged adjacent to each other, their central axes can be aligned so that their respective target ports 101 are distributed toward each other along a common circumference to maintain the regularity of the overall layout.

[0043] In some embodiments, in a trapezoidal voltage regulating module 1, the target side 102 may be set as the side where the longer bottom side or two waists of the trapezoid are located. When arranged in this way, the bottom sides or waist lines of adjacent voltage regulating modules 1 may be aligned, and the target ports 101 are arranged facing each other along this direction to form a straight interface area, so as to achieve a tighter arrangement and connection in a limited space.

[0044] In some embodiments, in an irregularly shaped voltage regulating module 1, surfaces that are both conducive to the alignment of ports of adjacent voltage regulating modules 1 and convenient for wiring can be selected as the target side 102. For example, the target side 102 can be set as the portion of the irregularly shaped voltage regulating module 1 that is closest to a rectangular or circular feature, so that the target ports 101 are arranged facing each other along these structures.

[0045] It should be noted that the present application does not specifically limit the specific form and type of the voltage regulating module 1, that is, those skilled in the art can adjust its type according to actual conditions. The above situation is only an exemplary description of the forms in which the target side 102 can be set in different types of situations of the voltage regulating module 1 in the present application, but is not limited to the situations described in the above embodiments.

[0046] In some embodiments, the target port 101 of the voltage regulating module 1 has a plurality of pins 103 , and the plurality of pins 103 of a pair of adjacent voltage regulating modules 1 may be symmetrically arranged.

[0047] The target port 101 of each voltage regulating module 1 may be provided with a plurality of pins 103, which are used to connect to the power supply end of the energy storage unit 2 to realize power supply. The pins 103 of adjacent voltage regulating modules 1 may be symmetrically arranged, that is, their positions and spacings in space may have a mirror-symmetric relationship, so that one energy storage unit 2 can simultaneously supply a pair of voltage regulating modules 1. By symmetrically arranging the pins 103 of adjacent voltage regulating modules 1, the wiring between the energy storage unit 2 and the voltage regulating module 1 is made more regular and symmetrical, which helps to reduce cross wiring.

[0048] In some embodiments, the DrMOS chip may be a square structure, with pins 103 for connecting to other modules arranged around it. In order to achieve mirror symmetry of the multiple pins 103 of the target port 101 of a pair of voltage regulating modules 1, the internal structure of the pair of voltage regulating modules 1 may be flipped accordingly to avoid wiring crossing.

[0049] In some embodiments, the number of voltage regulation modules 1 can be n, where n is a positive integer greater than or equal to 2; when n is an even number, the voltage regulation modules 1 form n / 2 pairs, each pair of voltage regulation modules 1 are symmetrically arranged, and the target ports 101 are adjacent and share a energy storage unit 2; when n is an odd number, the first n-1 voltage regulation modules 1 form (n-1) / 2 pairs, each pair of voltage regulation modules 1 are symmetrically arranged, and the target ports 101 are adjacent and share a energy storage unit 2, and the nth voltage regulation module 1 is separately configured with a energy storage unit 2.

[0050] The number of the voltage regulating modules 1 may be n, where n is a positive integer greater than or equal to 2, so that the power management module can flexibly configure different numbers of voltage regulating modules 1 according to actual application requirements.

[0051] When n is an even number, the n voltage regulating modules 1 are divided into n / 2 pairs. Each pair of voltage regulating modules 1 can be symmetrically arranged, that is, their layout, pin 103 distribution and other features present a mirror symmetric relationship. In addition, the target ports 101 of each pair of voltage regulating modules 1 are adjacent and can share an energy storage unit 2, making the wiring inside the power management module more regular.

[0052] When n is an odd number, the first n-1 voltage regulating modules 1 are also divided into (n-1) / 2 pairs, each pair can be symmetrically arranged and share an energy storage unit 2. Since the nth voltage regulating module 1 cannot be paired, it can be configured with an energy storage unit 2 alone. This structure takes into account the symmetry and resource allocation in the case of even and odd numbers of modules.

[0053] Regardless of whether n is an even number or an odd number, the power management module can achieve symmetrical setting and sharing of the energy storage unit 2, thereby reducing the number of the energy storage units 2, improving compactness, and reducing costs.

[0054] like Figure 7 As shown, in some embodiments, there can be 7 voltage regulation modules 1, which are combined in the ratio of 4:2:1 to form a first power supply group, a second power supply group, and a third power supply group; the first power supply group, the second power supply group, and the third power supply group are respectively used to be electrically connected to the power supply of the functional module 5.

[0055] The first power supply group can be composed of 4 voltage regulation modules 1, which can adopt parallel, series or mixed topology to cope with high power requirements or provide a wide voltage regulation range, and is suitable for providing high current and stable voltage output for the core components of the motherboard of the functional module 5 (such as central processing unit (CPU), graphics processing unit (GPU), storage controller and solid state drive (SSD), microcontroller (MCU), etc.). The second power supply group can include 2 voltage regulation modules 1, the design principle is similar to the first power supply group, but the scale is smaller, which is suitable for providing precise voltage control for components with moderate power requirements. The third power supply group can be composed of 1 voltage regulation module 1, which is specially designed to power low-power or auxiliary functional components.

[0056] Taking DrMOS chips as an example, 4 DrMOS chips are used as the first power supply group, which are mainly responsible for providing high current output, so that each component of the motherboard can obtain sufficient and stable energy supply. 2 DrMOS chips form the second power supply group, focusing on precise voltage control to ensure that each component works in the best state. The remaining 1 DrMOS chip is used as the third power supply group, which plays an overcurrent protection role and provides additional safety protection for the entire power supply system.

[0057] The power management module provided in the embodiment of the present application achieves dynamic power matching and enhances system reliability by grouping the voltage regulation modules and independently connecting them to the power supply. Especially in the application scenario using DrMOS chips, it can effectively ensure the stable and efficient power supply of various components of the motherboard.

[0058] In order to realize that one energy storage unit 2 can simultaneously support the power supply of at least one pair of voltage regulating modules 1, in some embodiments, such as Figure 2 As shown, multiple voltage regulating modules 1 include: a first voltage regulating module and a second voltage regulating module. The first voltage regulating module can be connected to the energy storage unit 2 through a first branch 3, and the second voltage regulating module can be connected to the energy storage unit 2 through a second branch 4. When the first branch 3 transmits an electrical signal to the first voltage regulating module, the second branch 4 does not transmit an electrical signal.

[0059] In the power management module, the first voltage regulating module can be connected to the energy storage unit 2 through the first branch 3, and the second voltage regulating module can be connected to the same energy storage unit 2 through the second branch 4. These two branches constitute independent power supply paths, serving the first voltage regulating module and the second voltage regulating module respectively. When the first branch 3 transmits an electrical signal to the first voltage regulating module, the second branch 4 does not transmit an electrical signal. This means that the electrical signal transmission of the two branches is mutually exclusive, that is, at the same time, one branch can be in working state and the other branch can be in silent state.

[0060] By not transmitting electrical signals through the second branch 4 when the first branch 3 transmits electrical signals to the first voltage regulating module, effective resource scheduling can be achieved to avoid excessive pressure on the energy storage unit 2 caused by the two branches working at the same time. The energy storage unit 2 can meet the independent power supply requirements of the first voltage regulating module and the second voltage regulating module by switching the power supply status of the first branch 3 and the second branch 4 without the need for additional capacity expansion, thereby saving energy.

[0061] In some embodiments, the power management module also includes: a control unit 6, used to output a control signal; a frequency division unit 7, which can be electrically connected to the control unit 6, and is used to divide the control signal to form and output a frequency division control signal, and the first voltage regulation module and the second voltage regulation module respectively receive the frequency division control signal.

[0062] like Figure 5As shown, the control unit 6 is an electronic subsystem or integrated circuit that can generate and / or process control signals, and can generate a pulse width modulation (PWM) signal to control the switch duty cycle of the voltage regulation module 1, thereby adjusting the output voltage. The frequency division unit 7 is an electronic circuit or integrated circuit for frequency division of the input signal. According to a preset frequency division coefficient, a periodic control signal can be decomposed into multiple sub-signals with different phase offsets, so as to achieve accurate time synchronization and interleaved operation between multiple voltage regulation modules 1. By dividing the control signal output by the control unit 6 to generate an accurate frequency division control signal, the first voltage regulation module and the second voltage regulation module can be accurately turned on and off according to a predetermined timing (such as staggered operation in static and dynamic states).

[0063] In related technologies, such as Figure 4 As shown, PWM IC (Pulse Width Modulation Integrated Circuit) is usually used to turn on all phases at the same time to adjust the voltage. This method requires a large number of capacitors to provide transient current support. In contrast, the power management module in this embodiment improves the PWM control principle, which can make the first voltage regulation module and the second voltage regulation module maintain staggered operation in both static and dynamic states. Figure 6 As shown in the figure, at any time one phase is turned on and the other phases remain off. This staggered working mechanism significantly reduces the number of capacitors required, reduces system cost, and helps optimize the spatial layout of the power management module.

[0064] In some embodiments, the phases of the frequency division control signals received by the first voltage regulation module and the second voltage regulation module may differ by 180 degrees.

[0065] The frequency division unit 7 can receive a PWM (pulse width modulation) signal output by a control unit 6 as input. The frequency division unit 7 performs frequency division processing on the input PWM signal to generate two sub-signals. The two sub-signals can be set to have a phase difference of 180 degrees, that is, the phase of one sub-signal just lags behind or leads the phase of the other sub-signal by half a cycle (i.e., half a PWM cycle). For example: the frequency division unit 7 can include two asynchronous counters, one for generating the first sub-signal (referred to as sub-signal A), and the other for generating the second sub-signal (referred to as sub-signal B). Sub-signal A is triggered directly following the rising edge (or falling edge) of the input PWM signal, while sub-signal B is triggered at the next rising edge (or falling edge) of the input PWM signal. In this way, sub-signal B will lag behind sub-signal A by half a PWM cycle, forming a 180-degree phase difference. Finally, the two frequency division control signals with a phase difference of 180 degrees are connected to the gate input terminals of the first voltage regulation module and the second voltage regulation module respectively. Ensure that sub-signal A controls the first voltage regulating module and sub-signal B controls the second voltage regulating module, so that when one of the voltage regulating modules is turned on (ie, the gate is at a high level), the other voltage regulating module is turned off (ie, the gate is at a low level).

[0066] It should be noted that the present application does not specifically limit the specific form and type of the voltage control unit 6 and / or the frequency division unit 7, that is, those skilled in the art can adjust their types according to actual conditions. The above situation is only an exemplary description of the forms in which the control unit 6 and / or the frequency division unit 7 in the present application can be set, but is not limited to the situations described in the above embodiments.

[0067] By keeping the switch states of the first voltage regulating module and the second voltage regulating module opposite at all times, it is possible to achieve that one energy storage unit 2 supports the operation of the pair of voltage regulating modules 1 at the same time. The energy storage unit 2 stores energy when one module is working and releases energy when the other module is working, thereby improving the utilization rate of energy storage resources.

[0068] In some embodiments, the power management module includes a control module and a switch element. The switch element can be set on the first branch 3 and the second branch 4. The control module is communicatively connected with the switch element, and the control module is used to control the switching frequency of the switch element.

[0069] The control module has the ability to generate and send control instructions to the switch element. A switch element can be configured in each of the first branch 3 and the second branch 4. The switch element (such as MOSFET, IGBT, relay, etc.) can receive the instruction of the control module and perform the opening and closing operation accordingly to control the on and off state of the corresponding branch.

[0070] By precisely adjusting the frequency of the switch elements through the control module, when the first branch 3 transmits an electrical signal to the first voltage regulating module, the switch elements of the second branch 4 remain in the closed state, that is, no electrical signal is transmitted, and vice versa. The energy storage unit 2 can supply power to one voltage regulating module 1 at the same time, avoiding the two branches from taking power from the energy storage unit 2 at the same time. By orderly switching and dynamically scheduling the power supply status of the first branch 3 and the second branch 4, the energy storage unit 2 can meet the independent power supply requirements of the first voltage regulating module and the second voltage regulating module without the need for additional capacity expansion, and avoid excessive pressure on the energy storage unit 2 caused by the simultaneous operation of the two paths, thereby achieving effective management and efficient utilization of electric energy resources.

[0071] An embodiment of the present application provides an electronic device including: a power management module and a power supply; the power management module is electrically connected to the power supply; the power management module includes multiple voltage regulation modules 1, the voltage regulation module 1 is used to adjust the voltage output by the power supply, and the voltage regulation module 1 includes a target port 101; an energy storage unit 2, the power supply end of the energy storage unit 2 is connected to the target ports 101 of the multiple voltage regulation modules 1; the target port 101 is used to receive the power supply signal of the energy storage unit 2.

[0072] The power supply provides basic power for the entire system, and the power management module can be responsible for effectively managing the input power and providing the system with a suitable operating voltage. The power supply and power management module can be arranged on the motherboard of the electronic device, and the motherboard is provided with a special wiring path and interface to ensure a stable electrical connection between the power supply and the power management module.

[0073] By including a power management module with multiple voltage regulating modules 1, the electronic device can provide accurate and stable voltage for the internal system, meet the specific requirements of different loads for working voltage, and help improve the performance of the device and extend its service life. The energy storage unit 2 is a device for temporarily storing and releasing electric energy. Its power supply end can be connected to the target port 101 of multiple voltage regulating modules 1, and can deliver electric energy to each voltage regulating module 1 when needed.

[0074] The electronic device provided in Example 4 of the present application realizes the sharing of energy storage resources by connecting the power supply end of an energy storage unit 2 to the target ports 101 of multiple voltage regulation modules 1, thereby reducing the number of energy storage units 2 and significantly improving the space utilization of the mainboard.

Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
