Abstract

An inductively loaded switching transistor circuit for use in the DC-DC converter includes an inductive load and a switching transistor coupled to the inductive load for conducting current flowing therethrough when the switching transistor is on. A drive circuit is provided which is coupled to the switching transistor for supplying a drive current thereto, and feedback means are provided for adjusting the amount of base drive supplied to the switching transistor from the drive circuit. The drive current is varied substantially linearly with respect to the current flowing through the inductive load.
