イツチング電源装置。 In addition to the constant output terminal, the device has a power output terminal that is derived from a switching element that is connected or disconnected by a control signal from the device that supplies power from the constant output terminal, and that supplies power to the device. In the multi-output switching power supply device, the multi-output switching power supply device includes an overcurrent protection circuit unit that maintains the switching element in an off state by detecting an overcurrent flowing to the power supply output terminal due to The overcurrent protection circuit is interposed and connected between the overcurrent protection circuit and the overcurrent protection circuit, and turns on the switching element when the control signal is turned on, turns off the switching element when the control signal turns off, and puts the overcurrent protection circuit into a normal state. A multi-output switching power supply device, characterized in that it is provided with a control circuit section for restoring the power.
