Title:
SWITCHING REGULATOR
Document Type and Number:
Japanese Patent JPS6152155
Kind Code:
A
Abstract:
PURPOSE:To simplify a circuit configuration, to reduce the heat and to improve the reliability by commonly using a transistor for switching as part of an auxiliary power source. CONSTITUTION:When a power source is turned ON, a base current is flowed through a resistor R4 to a transistor T3, amplified and supplied to a pulse generator PG. The pulse generated from the generator PG is supplied through an AC coupling condenser C4 to the base side of the transistor T3, which is thus switched. When the transistor T3 is turned ON, a capacitor C1 is charged, while when the transistor is turned OFF, it is discharged to hold the operation of the generator PG.
