Abstract
A circuit for driving a MOSFET () includes a capacitor () and a switch () connected to a gate () of the MOSFET. The circuit applies a charge pulse to the gate of the MOSFET so as to switch the MOSFET between one of an on state and an off state and the other of the one state and the off state. The duration of the pulse is such that the pulse is substantially complete prior to switching of the MOSFET. The pulse causes a voltage on the gate for a short period to be raised above a maximum gate-to-source rating of the MOSFET, thereby to improve the switching speed of the MOSFET.
