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.
Claims7
Driver circuit for driving a switching transistor and a MOS-transistor, both transistors being connected in series with a primary winding of a transformer and said MOS-transistor being arranged between said switching transistor and ground, and a switching voltage being applied to a gate electrode of said MOS-transistor,
- said driver circuit comprising a driver transformer for driving said switching transistor and an output stage for driving said driver transformer, said switching voltage being derived also from an output of said driver circuit, and said MOS transistor being a Low Voltage POWER MOS-transistor and said switching transistor being a power switching transistor of a line deflection output stage of a television receiver or of a switch mode power supply circuit.
