Abstract:
1. A chip module, comprising: a conductive pattern formed from at least a portion of a lead frame, said conductive pattern having a plurality of pads for electrical coupling thereto; a power integrated circuit, first and second capacitors, and a passive component, wherein said power integrated circuit comprises a first switching transistor coupled to a first DC rail and a switch connection point, and a second switching transistor coupled to a second DC rail and said switch connection point, said power integrated circuit and said passive component being separate components that are bonded to said plurality of pads by solder; wherein said conductive pattern is disposed to electrically interconnect said switch connection point of said power integrated circuit with said passive component without using bonding wires, wherein said first capacitor is coupled to said first and second DC rails, and wherein said second capacitor is coupled to said passive component and said second DC rail; and wherein said power integrated circuit is bonded to a first surface of said conductive pattern by solder, and wherein said passive component and said first and second capacitors are bonded to a second surface of said conductive pattern by solder, said first and second surfaces of said conductive pattern being on opposite sides of said conductive pattern, said power integrated circuit having a bottom integrated circuit surface facing opposite said first surface, said bottom integrated circuit surface being exposed for coupling to at least one of a heat sink and a main system circuit board.
