Abstract
An information handling system includes a power supply and a power assist unit. The power supply powers a power rail. The power assist unit includes a power storage element, a converter including a semiconductor device coupled to provide power from the power storage element to the power rail, and a controller configured to receive a load indication that indicates a power demanded by the load and to provide an intermediate output based upon the load indication. The controller includes a boost element to receive the intermediate output and to provide a controller output. The controller output is a sum of a bias voltage level provided by the bias element and the intermediate output. The controller output is coupled to a gate terminal of the semiconductor device. The converter provides power from the power storage element to the power rail in response to the controller output.
