Converter control circuit

Abstract

There is provided a converter control circuit including: a high-side switching element connected between an input voltage terminal and an inductive load; a low-side switching element connected between the inductive load and a reference potential; a drive circuit configured to drive a gate of the switching elements; a drive switch connected to the gate of at least one of the switching elements in parallel with the drive circuit; and a drive switch control circuit switching the drive switch from ON to OFF when the gate voltage of the switching element with the gate connected to the drive switch reaches a prescribed threshold while the switching element is driven by the drive circuit.

Dependencies are inferred from the claim text.
