Abstract
A control circuit for a power converter apparatus includes a reference voltage source that generates a predetermined reference voltage; an output voltage detection circuit having a capacitor that charges the output voltage or a corresponding voltage, the output voltage detection circuit detecting a drop in the output voltage based on a voltage across the capacitor; a feedback voltage output circuit including two voltage-divider resistors connected in series with each other with a voltage divider ratio set according to the reference voltage and the output voltage, the feedback voltage output circuit outputting a feedback voltage obtained by dividing the output voltage; a voltage comparison circuit that compares the reference voltage with the feedback voltage, and outputs a comparison result signal; and a drive control circuit configured to control intermittent operation in accordance with the comparison result signal and a detection signal of the output voltage detection circuit.
