Abstract

A high efficiency switching circuit, which may be monolithically integrated, includes a power output transistor which is driven to switch by means of a second transistor coupled to its control terminal. Circuit components for charge extraction are connected to the base terminals of both transistors and are activated by an enabling circuit having a control terminal and an input terminal connected to the collector terminal of a third transistor having its emitter and base terminals respectively connected to the emitter terminal and the base terminal of the second transistor.
