PWM IC A method for saving a system energy by using a PWM control IC

摘要

The present invention relates to a system energy saving method through a PWM control IC which improves a technology being currently actively developed which blocks standby power to provide a differentiated optimum CPU core supply voltage and frequency in accordance with the CPU use of a computer system in the computer system having various operating modes (in one example, S0-S5 mode) so as to save power, find the entire operation state of a CPU through the PWM control IC to differentially supply power and optimize power consumption in accordance with a use amount of the CPU as well as the operation mode (S0-S5 mode) of the system.
