Abstract:
A power supply apparatus capable of switching an output voltage Vout based on an external control signal includes a control unit configured to perform control to stop an output from the power supply apparatus in a case where a voltage applied to a Vcc terminal is higher than a predetermined voltage Vovp. The Vcc terminal is connected to a primary-side auxiliary winding of a transformer via a regulator and the control unit operates based on power supplied to the Vcc terminal in normal operation. A base of an NPN transistor included in the regulator is connected to a ground via a first resistance R 1  and a first zener diode ZD 1 . A second resistance R 2  is provided between the base and a collector of the NPN transistor.

Claim (Index 3):
The power supply apparatus according to  claim 1 , wherein\n a PNP transistor is further provided between the collector and the base of the NPN transistor in parallel to the second resistance R 2 , an emitter of the PNP transistor is connected to the collector of the NPN transistor, a collector of the PNP transistor is connected to the base of the NPN transistor, a base of the PNP transistor is connected to the emitter of the PNP transistor via a third resistance, and the base of the PNP transistor is further connected to the ground via a fourth resistance and a third zener diode ZD 3 , and in a case where a voltage in the third zener diode ZD 3  is denoted by VZ 3 , the voltage VZ 3  satisfies Formula (3) below:\n Vauxer\u2212Vovp\u2212Veb>VZ3>Vaux\u2212Vovp\u2212Veb \u2003\u2003(3)
