したことを特徴とするスイッチングレギュレータ。[Claims for Utility Model Registration] A commercial AC power source is rectified into an input DC voltage by a rectifier, and this input DC voltage is applied to a switching unit connected to the primary winding of the converter transformer. An AC voltage for forming an output DC voltage is induced in the next winding, and the voltage of the tertiary winding of the converter transformer that detects this AC voltage is applied to a drive circuit. In the switching regulator, the switching regulator is driven by the output DC voltage and controls the switching unit according to fluctuations in the output DC voltage, wherein the switching regulator is provided between the rectifier unit and the drive circuit,
The power supply unit supplies auxiliary power to the drive circuit until the voltage of the next winding rises, and the auxiliary power supply unit derives the auxiliary power only at the moment when the commercial AC power is turned on. switching regulator.
