チングレギュレータ。The primary winding of the converter transformer is connected to a switching transistor that oscillates due to a base current supplied from a drive winding that induces a voltage in the primary windings of loads T, C, and C through a base current limiting resistor, and a control unit that detects a voltage corresponding to the voltage of the secondary winding of the converter transformer obtained by the oscillation output, compares it with a reference voltage, amplifies the error, and controls the switching period of the switching transistor; , a detection paper for detecting the collector current of the switching transistor;
The present invention is characterized by comprising a first transistor that turns on when the voltage drop across the detection resistor becomes larger than a set value, and a second transistor that is driven by the first transistor and can vary the value of the base current limiting resistor. switching regulator.
