Abstract
Disclosed is an inrush current suppressor circuit of a power supply circuit that supplies stand-by voltage from AC voltage. At a stand-by mode, only a diode and a resistor for suppressing inrush current are provided, and a capacitor provided in common between a stand-by power supply part and a start-up power supply part is charged, so that the inrush current is suppressed at both of stand-by and start-up modes and the number of devices of a circuit and power consumption are reduced.
