Abstract
An apparatus includes a capacitor coupled to a power switch, wherein the capacitor is configured to provide a negative gate voltage to the power switch when a turn-off signal is applied to a gate of the power switch, and a sink and source power supply coupled to the capacitor, wherein the sink and source power supply has a first current limit for controlling a sink current flowing from the capacitor to the sink and source power supply, and a second current limit for controlling a source current flowing from the sink and source power supply to the capacitor.
