ABSTRACT:
A switching circuit is improved in efficiency by including a switching corrector circuit for feeding back reversed polarity, differentiated switching pulses to the base of the switching transistor. In addition, temperature stability is achieved by providing a constant current source for a drive transistor which drives the switching transistor and for a control transistor which controls the drive transistor on the basis of the detected output of the circuit.
