Short Content:     In the past five years, Intel and the AMD CPU performance had the remarkable enhancement. The CPU performance's enhancement request is more precise for its power supply's voltage regulator and is complex.     The power source designers face how does the biggest challenge is satisfy a bigger power, the smaller voltage allowance as well as the quicker transient response, and reduces power source's total cost. This article has discussed the pulse-duration modulation (PWM) development process, the heterogeneity ...
