Description

technical field [0001] The invention relates to an intelligent scheduling high-efficiency power supply manager and a control method thereof. Background technique [0002] Traditionally, with SoC (system on chip) widely used in portable electronic devices, power management chips responsible for the distribution and transformation of electric energy have become indispensable. In order to meet the demanding requirements of portable electronic devices, smaller size, lower power consumption and higher efficiency are the future development direction of power management chips. In the power management chip, there are three types of circuits used to realize voltage conversion: low dropout linear regulator (LDO), switched capacitor regulator and switched inductor regulator. Among them, LDO with simple structure has the highest market share. But its conversion efficiency will decrease with the increase of input voltage. [0003] At present, domestic industrial products and academic ...
