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.

Claim (Index 5):
The switching power supply circuit according to  claim 1 , wherein\n the shut-down circuit includes: a PNP transistor having an emitter connected to an output of the second rectifying element, a collector connected to the power supply terminal, and a base; a first adjustment resistor and a Zener diode connected in series between the base and a ground; a voltage supply resistor disposed between the output of the second rectifying element and the base; a second adjustment resistor having one end connected to the collector; and a fourth rectifying element disposed between an other end of the second adjustment resistor and the power supply terminal, wherein the set voltage is a Zener voltage for the Zener diode.
