Title:
POWER SUPPLY CIRCUIT AND METHOD, ELECTRONIC DEVICE AND COMPUTER-READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/087781
Kind Code:
A1
Abstract:
A power supply circuit and method, an electronic device, and a computer-readable storage medium. The power supply circuit is used for supplying power to a processor, and comprises: an AVS module (42) used for monitoring and outputting the performance of the processor (41); and a switching power supply (43) used for adjusting the power supply voltage provided to the processor (41) according to the output of the AVS module (42), wherein the switching frequency of the switching power supply (43) is greater than 10 MHz. The switching frequency used by the switching power supply (43) in the power supply circuit is greater than 10 MHz, such that the switching power supply (43) quickly stabilizes the power supply voltage to a power supply voltage value required by the processor (41) according to the voltage requirements of the processor (41) output by the AVS module (42), and the adaptive adjustment time of the AVS module (42) is correspondingly shortened, thereby effectively reducing the working loss of the processor (41).
