ABSTRACT:
A switching regulator includes an inrush current protective resistor and a starter circuit for a pulse width modulator consisting of a starting resistor and a capacitor. At initial starting mode, the inrush current protective resistor is connected to the starter circuit, and after starting both of the inrush current protective resistor and starting resistor are disconnected so as to reduce power dissipation or consumption thereby. At the same time, a DC voltage source for the pulse width modulator is derived from a rectified secondary voltage through the starting capacitor.
