Abstract

See full text

A DCR detecting circuit is parallel connected to the inductor of a self-clocking PWM buck converter which performs a trigger control of a PWM signal by an output feedback, to detect the current signal on the inductor to provide a large enough ripple to be combined into the output feedback, so as to enhance the system stability, while remains the small output ripple, without additional power loss.
