Abstract
A controller of a power conversion circuit generates PWM signals to control output stage circuits to provide an output voltage and a load current to an output terminal. The controller includes a sensing circuit, a comparison circuit, a PWM generation circuit and a control loop. The sensing circuit generates a current sensing signal related to load current. The comparison circuit compares the current sensing signal and a default value representing a current threshold to generate a comparison result. The control loop, coupled to the output terminal, the PWM generation circuit and the comparison circuit, generates a trigger signal according to a reference voltage and the output voltage to control the PWM generation circuit to generate PWM signals. When the comparison result indicates that the load current exceeds current threshold, the control loop temporarily stops providing trigger signal to PWM generation circuit to delay the generation of PWM signals.
