A circuit and method for reducing losses in a DC/DC converter by optimizing gate drive voltage. The circuit and method detect a change in the output load, or more specifically the output current, and adjust the gate voltage accordingly; in other words, providing adaptive gate drive voltage. In response to a reduction of output current, the invention reduces the gate voltage so as to reduce both conduction and switching losses in the semiconductor switching devices in the output stage.
