Patent ID: 7868432

Claim:
A multi-chip module comprising: a metal leadframe structure including a first lead, a second lead, a third lead, a fourth lead, and at least two independent die mounting pads electrically isolated from one another, the at least two independent die mounting pads including a first pad for mounting at least one integrated circuit chip and a second pad for mounting at least one transistor device chip; an integrated circuit chip mounted on the first pad; a first MOSFET transistor mounted on the second pad, the first MOSFET transistor having a gate electrode, a source electrode, and a drain electrode, the first MOSFET transistor being mounted so that its drain electrode faces the second pad and is electrically coupled to the second pad; a second MOSFET transistor mounted on the second pad, the second MOSFET transistor having a gate electrode, a source electrode, and a drain electrode, the second MOSFET transistor being mounted so that its drain electrode faces the second pad and is electrically coupled to the second pad; a first plurality of bonding wires having a first diameter connecting the integrated circuit chip to the first and second leads and to at least the gate electrodes of the first and second MOSFET transistors; and a second plurality of bonding wires having a second diameter greater than the first diameter connecting the source electrodes of the first and second MOSFET transistors to the third and fourth leads, respectively; and wherein said mounting pads are exposed on the back side of the module and wherein the module includes an epoxy molding material.
