Abstract:
1. A monolithic power converter package comprising: a monolithic die over a substrate, said monolithic die integrating a driver integrated circuit (IC) with a control power transistor and a sync power transistor connected in a half-bridge; a high side power input and a power output of said half-bridge each being disposed on a top surface of said monolithic die; said high side power input being electrically coupled to said substrate through a high side power connection; said power output being electrically coupled to said substrate through a power output connection; a low side power input of said half-bridge comprising a plurality of through substrate vias that extend through said monolithic die to electrically connect a low side power pad to said monolithic die; said monolithic power converter package thereby achieving low resistive and inductive connections for said monolithic die, without using a bond wire for connection to said low side power input.
