。A switching circuit in which the primary winding of the transformer and a switching transistor are connected in series is connected in parallel to a DC power supply that has rectified and smoothed the AC input, and
A first output circuit includes a rectifier diode inserted into the output end of one of the secondary windings having the same polarity as the secondary winding, and obtains a DC output via a flywheel diode, a reactor, and a capacitor, and the primary winding of the transformer. A rectifier diode is inserted into the output end of the other secondary winding of different polarity, and a second output circuit obtains DC output via a capacitor.The voltage of the second output circuit is detected and a switching transistor is controlled. A single right type multi-output switching regulator comprising a control circuit for driving, and a circuit that receives a DC power source as input, is composed of a resistor, and a constant voltage diode, and generates a voltage slightly lower than the voltage of the second output circuit.
