  • Power switching circuit having a Darlington connected transistor pair
    Patent number: 4060758
    Abstract: A switching circuit has an output transistor between an input and an output conductor, and a drive transistor, the transistors being Darlington-connected. A transformer has one winding in the collector circuit of the drive transistor and another winding across the base-emitter junction of the output transistor, the windings being arranged so that a falling collector current to the drive transistor induces a reverse bias current in the base-emitter junction of the output transistor.
