POWER SUPPLY DEVICE FOR CENTRAL PROCESSING UNIT

摘要

A power supply device is configured for supplying electrical power to a central processing unit (CPU) of an electronic device. The CPU operates in a number of working modes. The power supply device includes a power supply module operating in a number of power supply modules corresponding to the working modes of the CPU, a number of compensation circuits respectively corresponding to the power supply modes, and a control module. The control module determines the working mode of the CPU and controls the corresponding compensation circuit to electrically connect to the power supply module to provide a loop compensation to the power supply module which improves stability and responding speed of the power supply module.
