Abstract

PURPOSE:To effectively start a switching regulator by switching it with a DC voltage from a rectifying circuit at the time of throwing a power source. CONSTITUTION:A DC voltage from a rectifying circuit 4 is supplied through a transistor 32 to circuits 15-17 at the time of throwing a switch 2, and the switching operation of the transistor is started. When the transistor 6 once starts switching, the DC voltage from a rectifying circuit 21 is supplied to the circuits 15-17 to perform the switching operation of the transistor 6, thereby maintaining the ordinary operating state. When an input voltage becomes extraordinarily high, the DC voltage from the rectifying circuit 4 becomes high, the voltage drop of a resistor 35 becomes high, and a transistor 41 becomes ON. Accordingly, a PWM pulse is not supplied to the transistor 6, and the transistor 6 becomes OFF and is protected.
