Abstract
A Safe Operating Area (SOA) adaptive gate driver for a switch mode power converter is disclosed. In response to a detection of a fault condition, the SOA adaptive gate driver may limit the peak current in a power transistor (e.g., power MOSFET) of the power converter by limiting the voltage applied to the gate of the power MOSFET or by limiting the current injected into the gate of the power MOSFET. The limited gate voltage or current may increase the margin between an SOA border and the turn-off locus of the drain voltage and current (Vand I) to ensure safe operation of the switch mode power converter during the fault condition.
