Abstract

A circuit includes an overshoot-and-undershoot (OU) signal generator generating a signal indicating detection of an overshoot or an undershoot of an output signal of the power converter. The circuit further includes a feedback signal modulator receiving a first feedback signal and the signal indicating detection of the overshoot or the undershoot and generating a second feedback signal in response to the first feedback signal and the signal indicating detection of the overshoot or the undershoot. The feedback signal modulator generates the second feedback signal that is different from the first feedback signal during a predetermined time interval after the signal indicating detection of the overshoot or the undershoot has been asserted.
