Abstract
A power supply circuit includes a PWM controller capable of providing pulse signals to a CPU, and an I/O controller electrically coupled to the PWM controller and the CPU respectively. The I/O controller is capable of receiving voltage selection signals from the CPU and outputting a control signal to the PWM controller. The PWM controller is capable of adjusting pulse signals provided to the CPU according to the control signal.
