Abstract

A synchronous rectifier comprising a discrete switching device and a controller for controlling the discrete switching device both mounted on a common die pad and packaged in a single package. The packaging of the discrete switching device and the controller together in a single package provides shortest path of connection between the ports of the controller and the switching device, enabling the controller to accurately sense voltage across the switching device thereby avoiding the effect of parasitic inductances and enabling the controller to enable/disable the switching device at the precise time, resulting in improved power consumption and better efficiency.
