Abstract: A power module includes a first die pad, a first switching element, a second die pad, a second switching element, an integrated circuit element, an encapsulation resin, and a lead frame assembly. The encapsulation resin encapsulates the first switching element, the second switching element, and the integrated circuit element. The lead frame assembly includes an outer lead and an inner lead. The lead frame assembly includes a first lead frame and a second lead frame. The first lead frame includes a first inner lead connected to the first die pad and a first outer lead connected to the first inner lead. The second lead frame includes a second inner lead connected to the second die pad and a second outer lead connected to the second inner lead.
