Abstract
Provided is a current-source gate driver for use with a switching device having a gate capacitance, including an input terminal for receiving a DC voltage; a first switch connected between the input terminal and an output terminal; a second switch connected between the output terminal and a circuit common; a series circuit comprising a first capacitor and an inductor, the series circuit connected between the input terminal and the output terminal; wherein the gate capacitance of the switching device is connected between the output terminal and the circuit common. The current-source gate driver improves efficiency of the power switching devices of a voltage regulator module or other switching converter.
