Abstract: A transformer for module integration includes a first layer of magnetic material having an outer edge, a second layer of magnetic material having an outer edge, and an isolation layer positioned between the first layer of magnetic material and the second layer of magnetic material along a primary axis. The transformer includes a first inductive element positioned in the first layer of magnetic material and a second inductive element disposed opposite of the first inductive element and in the second layer of magnetic material.

Abstract: Methods and apparatus for isolation barrier with magnetics. In an example arrangement, an apparatus includes an isolation laminate including a dielectric core having a first surface and a second surface opposed to the first surface; at least one conductive layer configured as a first transformer coil overlying the first surface; a first dielectric layer surrounding the at least one conductive layer; a first magnetic layer overlying the at least one conductive layer; at least one additional conductive layer configured as a second transformer coil overlying the second surface; a second dielectric layer surrounding the at least one additional conductive layer; and a second magnetic layer overlying the at least one additional conductive layer. Methods for forming the isolation barriers and additional apparatus arrangements are also disclosed.
