Abstract: A rectifying element is connected to an auxiliary winding. The shut-down circuit receives a bias voltage output from the rectifying element. A shut-down circuit stops supply of power to a power supply terminal of the power supply control IC when the bias voltage is less than a set voltage. A power supply control IC controls a ratio of on-time to a switching cycle of the switching element, based on a current sensing voltage generated at a current sense resistor. The power supply control IC causes the switching operation of the switching element to stop when a voltage at the power supply terminal decreases to a stop voltage or less.
