Patent ID: 8085553

Claim:
A power switch assembly, comprising: a flip-chip type integrated circuit chip including a distributed transistor fabricated therein having a plurality of source regions and a plurality of drain regions, the flip-chip type integrated circuit chip having a surface with a first plurality of flip-chip interconnects and a second plurality of flip-chip interconnects, the first plurality of flip-chip interconnects connected to the source regions, the second plurality of flip-chip interconnects connected to the drain regions; and a lead-frame with a plurality of lead sections including a first lead section and a second lead section, each of the plurality of lead sections extending in parallel with a first axis, the second lead section spaced apart from the first lead section in a second direction orthogonal to the first axis, the first lead section and the second lead section at least partially overlapping along the first axis, wherein each of the plurality of lead sections includes a contact portion and an extended portion extending laterally from the contact portion, the extended portion of the first lead section extends from the contact portion of the first lead section in a first direction parallel to the first axis, the extended portion of the second lead section extends from the contact portion of the second lead section in a direction opposite to the first direction, and the contact portion of the first lead section and the contact portion of the second lead section do not fully overlap along the first axis, and wherein each of the plurality of lead sections includes a first side and an opposite second side, the first side of the first lead section contacting at least two of the first plurality of flip-chip interconnects, the first side of the second lead section contacting at least two of the second plurality of flip-chip interconnects, the second side of the first lead section in the contact portion of the first lead section configured to contact a first contact area on a printed circuit board, and the second side of the second lead section in the contact portion of the second lead section configured to contact a second contact area on the printed circuit board.
