Abstract: A control circuit with protection circuit for power supply according to the present invention comprises a peak-detection circuit and a protection circuit. The peak-detection circuit detects an AC input voltage and generates a peak-detection signal. The protection circuit generates a reset signal to reduce the output of the power supply in response to the peak-detection signal. The present invention can protect the power supply in response to the AC input voltage effectively through the peak-detection circuit.
