Abstract :
The digitally controlled DC-DC power converter has an advantage of high reliability, high controllability and high flexibility. A new digital controller for PWM and/or PFM controlled switching DC-DC power converters is presented, which is versatile in general use such as switching frequency from 20 kHz to 500 kHz, hard-switching and soft-switching
