Abstract
A power semiconductor package comprises a lead frame, a low side field-effect transistor (FET), a high side FET, a capacitor, a resistor, an inductor assembly, a first plurality of bonding wires, and a molding encapsulation. In one example, an entirety of the inductor assembly is disposed at a position higher than an entirety of the low side FET, higher than an entirety of the high side FET, and higher than an entirety of the first plurality of bonding wires. In another example, a bottom surface of the low side FET and a bottom surface of the inductor assembly are co-planar.
