Abstract

A controller for protectively reducing an output of a converting circuit includes a feedback circuit, a logic control circuit, an over-state judgment circuit, and a protection control circuit, is disclosed. The feedback circuit generates a modulation signal according to an output of a converting circuit. The logic control circuit is coupled to the feedback circuit and controls the converting circuit according to the modulation signal for stabilizing the output of the converting circuit. The over-state judgment circuit receives an over-state reference signal and a detecting signal, and generates a protection signal in response to levels of the detecting signal and the over-state reference signal. The protection control circuit is coupled to the logic control circuit and the over-state judgment circuit and controls the logic control circuit to lower the output of the converting circuit when receiving the protection signal.
