Abstract

A plurality of semiconductor die, which may be of diverse size and diverse junction pattern, are fixed to a common lead frame and within a common package. The semiconductor die are mounted on respective main pad areas that are laterally spaced from one another and which have respective heat sinks. The heat sinks extend from the boundary of the device package and form external pins that are available for external connection at the same or at different potentials. Isolated pins are also provided. The device package may be used for high and low side chopper circuits, synchronous regulator circuits, single-mode bridges, and the like.
