Claim 4:
5. The control circuit according to claim 4, wherein the output detection circuit comprises:
a reset signal generation module, configured to generate a reset signal according to the power supply voltage and a reference voltage;
a comparison module, configured to compare the feedback voltage of the output voltage with the preset voltage value to obtain a comparison result, and generate a comparison signal according to that comparison result;
a logic module, configured to generate a clock signal according to the comparison signal;
a control module, configured to perform a set operation according to the clock signal and a reset operation according to the reset signal, so as to generate a logic control signal, and control states of the current-limiting foldback control signal and the undershoot suppression signal according to the logic control signal.
