Abstract:
1. A semiconductor device comprising: a lead frame comprising an outer lead portion; an IC element comprising a switching element mounted on a main face of the lead frame; an inductor mounted on a back face of the lead frame; and a resin body configured to seal the lead frame, the IC element and the inductor, wherein the outer lead portion extends beyond the resin body, wherein the inductor and the lead frame are closely contacted with each other, wherein the IC element is disposed at a position corresponding to a center axis of the inductor, wherein the inductor and the IC element are electrically connected to each other, and wherein a wiring for a current path comprising at least one ground terminal and an input terminal, through which a main current of the switching element of the IC element flows, is disposed between a first terminal and a second terminal associated with the inductor.
