ABSTRACT:
A circuit and method for driving a field effect transistor is disclosed. A switching circuit includes a driver device having a signal input, a supply voltage input, and an output. The driver output is coupled to a JFET. A converter couples to the JFET and provides an output of the switching circuit. When enabled, a switching device couples this switching circuit output to the gate of the JFET, thus causing the JFET to be driven into conduction.
