Abstract

The invention relates to a power supply control method, a power supply control circuit, electronic equipment and a readable storage medium. The method comprises the steps: obtaining a battery voltage,carrying out the at least one voltage conversion on the battery voltage through a power supply chip if the battery voltage is higher than a preset voltage threshold, and outputting a converted voltage, wherein the converted voltage can be used by a to-be-powered device; and supplying power to the to-be-powered device by the converted voltage. In the prior art, the power supply chip for supplyingpower to the to-be-powered device in the electronic equipment can only perform voltage conversion on the voltage within a certain threshold range to supply the voltage to the to-be-powered device fornormal use. According to the invention, if the battery voltage is higher than the preset voltage threshold, the battery voltage is subjected to voltage conversion at least once through the power supply chip to output the converted voltage, and then the converted voltage is used for supplying power to the to-be-powered device, so that the voltage conversion frequency is reduced, the conversion efficiency of electric energy is improved, and the endurance time of the battery is prolonged.

Description

technical field [0001] The present application relates to the technical field of power management, in particular to a power supply control method, a power supply control circuit, electronic equipment, and a readable storage medium. Background technique [0002] With the development of the mobile terminal technology, the functions that the mobile terminal can realize are becoming more and more abundant, and accordingly higher requirements are put forward for the battery life of the mobile terminal. Traditionally, in the process of using a battery to supply power to a device to be powered, it is often necessary to perform multiple voltage conversions on the voltage of the battery to meet the power consumption requirements of the device to be powered. Obviously, in the process of performing multiple voltage conversions on the battery voltage, the power conversion efficiency is low, and thus greatly shortens the battery life.
