Abstract

PURPOSE: To prevent an abnormal current flowing beforehand by controlling an oscillating circuit made to perform a switching operation with detecting an over current of the primary side.
CONSTITUTION: A secondary winding N2 being as a secondary side of a transformer T constitutes an output portion. "On" and "off" of a transistor Q5 is controlled by controlling an oscillating frequency of an oscillating circuit OSC responding with a detected value of a detecting mean 2 and a stabilized voltage is supplied by controlling an output voltage. An emitter of a transistor Q5 of a driver circuit 1 is connected to a ground through a resistance R5. And an over current detecting circuit mean 3 utilizing a voltage drop due to a resistance R5 is provided and an operation of an oscillating circuit OSC is stopped by this detected output
