ABSTRACT:
The driver circuit for driving a switching transistor comprises a driver transformer for driving the switching transistor and an output stage for driving the driver transformer, and an output of the driver circuit is used for providing also said switching voltage. The switching voltage is derived advantageously from the primary winding of the driver transformer. Preferably a terminal of the primary winding of the driver transformer is directly wired to the gate electrode of the MOS transistor.
