Abstract

A voltage-isolated transformer and integrated circuit package includes a substrate with opposed first and second surfaces and including a plurality of conductive traces, with a recess disposed in the second surface. The plurality of conductive traces includes a first group and a second group that are galvanically separate. A magnetic core is disposed on the first surface of the substrate. The magnetic core can include a soft ferromagnetic material. First and second coils are configured about the magnetic core and connected to the first and second groups of conductive traces, respectively, with the first and second coils and magnetic core being configured as a transformer. First and second integrated circuit die are disposed in the recess on the second surface. A dam is disposed on the first surface of the substrate and surrounding the magnetic core. An encapsulant disposed in the dam and encapsulating the magnetic core.
