Abstract
A power supply circuit includes a transistor having a drain connected to an input voltage, a gate, and a source; a diode; a choke coil; a capacitor; a transformer; a control circuit that provides a drive signal for turning on and off the transistor to a primary winding of the transformer based on an output voltage; an overvoltage detection circuit that outputs an overvoltage signal when the output voltage is an overvoltage; and a short circuit that short-circuits the gate and the source of the transistor in response to the overvoltage signal.
