Abstract
A power semiconductor package comprises a lead frame, a semiconductor chip, and a molding encapsulation. The lead frame comprises an elevated section comprising a source section; a drain section; and a plurality of leads. The semiconductor chip includes a metal-oxide-semiconductor field-effect transistor (MOSFET) disposed over the lead frame. The semiconductor chip comprises a source electrode, a drain electrode, and a gate electrode. The source electrode of the semiconductor chip is electrically and mechanically connected to the source section of the elevated section of the lead frame. The semiconductor chip is served as a low side field-effect transistor as a flipped-chip connected to a heat sink by a first thermal interface material. A high side field-effect transistor is connected to the heat sink by a second thermal interface material. The low side field-effect transistor and the high side field-effect transistor are mounted on a printed circuit board.
