Abstract
A high side buck converter includes a high side transistor, a low side transistor, a sensor, a sensing window generator, an error amplifier, a first comparator and an on-time signal generator. The high side and low side transistors are coupled together to form a switch node which is used as the reference ground of the controller. The sensor senses the output voltage and generates a sensing signal. The sensing window generator generates a sensing window signal. The error amplifier amplifies the error between a feedback signal of the sensing signal and a reference signal during the sensing window, and generates an error signal. The first comparator compares the feedback signal with the error signal and generates a first comparison signal. The on-time signal generator generates an on-time signal based on the first comparison signal, so as to control the high side and low side transistors.
