Abstract

For isolation barrier with magnetics, 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 described.
