Patent ID: 7882482

Claim:
A high power switch-mode voltage regulator output stage, comprising: a semiconductor die comprising an array of switching elements individually including a source contact pad and a drain contact pad, and a plurality of gate driver circuits individually adjacent to and dedicated to drive one of said switching elements so that target amount of current is injected from said gate driver circuit to drive said corresponding switching element; and a lead frame attached to said semiconductor die, said lead frame comprising first and second electrical leads corresponding to a source and a drain connection, said first and second electrical leads having first and second plurality of finger shaped structures, respectively, wherein said first and second electrical leads are arranged so that said first and second plurality of finger shaped structures form an inter-digital pattern, and wherein said first plurality of finger shaped structures are in electrical contact with said source contact pads of said array of switching elements, and wherein said second plurality of finger shaped structures are in electrical contact with said drain contact pads of said array of switching elements.
