METHOD AND APPARATUS FOR DRIVING A POWER TRANSISTOR GATE

摘要

A gate drive circuit comprising a first switch (sw1) electrically coupled to a single-supply input voltage node, the first switch electrically coupling the voltage node with a first capacitor (Cs) if switched on; a second switch (sw2) electrically coupled to a ground node, the second switch electrically coupling the first capacitor with the ground node if switched on; and the first capacitor, a first capacitor lead of the first capacitor electrically coupled to the first and second switches and a second capacitor lead of the first capacitor arranged to connect with a power transistor gate.
