Abstract

A power converter comprises a first switch and a second switch connected in series between an input power source and ground, an inductor connected between a common node of the first switch and the second switch, and an output capacitor and a comparator having a first input connected to a reference, a second input configured to receive a sum of a first feedback signal and a second feedback signal and an output configured to generate a turn-on signal of the first switch, wherein the first feedback signal is proportional to an voltage across the output capacitor and the second feedback signal is generated by applying at least one low-pass filter to a switching ripple voltage.
