Filed: 2001-05-29
Abstract: PROBLEM TO BE SOLVED: To provide a self oscillating switching power unit equipped with a start/stop circuit having both a reliable start-up function and an oscillation stop function without malfunctioning. SOLUTION: In the switching power unit, as the power switch is turned ON to raise the voltage of the input power supply Vin, the voltage at the point a rises to exceed the constant voltage and then a transistor Tr2 is turned ON while a transistor Tr1 is turned OFF. At this time, a first switching element Q1 is turned ON due to the start voltage impressed on its control terminal to generate a voltage on a first drive coil T3. Such a voltage is returned to the point a via a feedback circuit F. This encourages the transistor Tr2 to turn ON and the transistor Tr1 OFF. Thus the first switching element Q1 rapidly turns ON to start oscillation.
