Zusammenfassung:	The present disclosure presents a circuit, a method, and a system to drive a half-bridge switch using depletion (D) mode compound semiconductor (III-V) switching transistors for a DC-DC converter using at least one driver to drive the switches of the circuit. Also included is at least one charge pump electrically connected to a gate of the transistor, to maintain a voltage that holds the transistor in an off-state. The circuit includes AC coupling capacitors to level shift a voltage and realize fast transistor switching.
