Abstract:
A power supply module includes a metallic clip including a plate having an area and a first and a second ridge on opposite sides of the plate. The ridges bent in the same direction away from the plate. The first and the second ridges conductively attached to the substrate, where the substrate is of insulating material integral with metal traces, the plate roofing over the substrate between the ridges. A first MOS field-effect transistor (FET) chip and, horizontally side-by-side, a second MOSFET chip are attached and wire bonded to the substrate under the plate. The drain of the first MOSFET is connected to the input terminal of the module, the source of the first MOSFET is tied to the drain of the second MOSFET, and the source of the second MOSFET, together with the second ridge, is connected to ground. A driver and controller chip is attached to the substrate under the plate and wire bonded to the gates of the first and second MOSFET. A capacitor is attached to the substrate under the clip plate and conductively connected to the first clip ridge and to the drain of the first MOSFET.

Claim (Index 9):
A method for fabricating a power supply module comprising:\n assembling passive electronic components including a capacitor on a substrate of insulating material integral with metal traces; assembling on the substrate, horizontally and side-by-side a chip, a first MOS field-effect transistor (FET), a chip with a second MOSFET, and a chip with a driver and controller circuit; connecting by wire bonding and traces the drain of the first MOSFET to the input terminal of the power supply module, the source of the first MOSFET to the drain of the second MOSFET, the source of the second MOSFET to ground, and the MOSFET gates to the driver-and-controller terminals; connecting the capacitor to the drain of the first MOSFET and the input terminal of the module; providing a metallic clip including a plate having an area and a first and a second ridge on opposite sides of the plate, the ridges bent in the same direction away from the plate; attaching the ridges conductively to the substrate so that the area of the plate forms a roof over the assembled chips and passive components, the first ridge is tied to the capacitor and the second ridge is tied to ground; and filling the space between the substrate and the clip with a packaging material, thereby encapsulating the assembled chips and passive components while leaving the outer surfaces of the clip and the substrate free of packaging material.
