ABSTRACT:
A monolithically integrable high-efficiency control circuit for the switching of transistors includes a first transistor whose base terminal is connected to a source of switching signals. A second transistor whose base is connected to a current generator, drives a third transistor which connected in series with the first transistor such that the first and third transistors are connected between two terminals of a supply voltage generator. The emitter terminal of the third transistor forms an output terminal of the control circuit and is connected to the collector terminal of the first transistor by means of a parallel connected diode and a resistor combination. The circuit also includes a fourth transistor, whose base terminal is connected through a resistor to the base terminal of the third transistor and whose collector and emitter terminals are respectively connected to the base terminal of the second transistor and to the collector terminal of the first transistor.
