Patent ID: RE42658

Claim:
A multi-chip module (MCM) for providing power circuitry on a computer motherboard, comprising: a ball grid array (BGA) substrate having a first surface and a second opposing surface; two power MOSFETs disposed on the first surface of the BGA substrate and connected in a half-bridge arrangement between an input voltage and ground; a MOSFET gate driver disposed on the first surface of the BGA substrate and electrically connected to respective gate inputs of the two power MOSFETs for alternatively switching the power MOSFETs to generate an alternating output voltage at a common output node between the power MOSFETs; and at least one diode disposed on the first surface of the BGA substrate and connected between the common output node and ground to minimize losses during deadtime connection periods; and an input capacitor disposed on the first surface of the BGA and connected between the input voltage and ground; wherein the input capacitor is located adjacent to, and spaced less than 1 cm from the first and second MOSFETs, and wherein the input capacitor and the first and second MOSFETs are positioned side-by-side.
