Abstract

A switched inductive storage element to enhance gate drive at turn-off is described herein. An inductive storage element (e.g., an inductor) may be switched between a supply node and a gate node of a gated device (e.g., a low-side device and/or a high-side device). While coupled to the supply node, the inductive storage element may be energized; and subsequently, while coupled to the gate node of the gated device, the inductive storage element may drive the gate node (i.e., the gate of the low-side and/or high-side device) below the local ground potential.
