Abstract
In examples, a transformer device comprises a first magnetic member; a second magnetic member; and a substrate layer between the first and second magnetic members. The substrate layer comprises a transformer coil. The transformer device includes a third magnetic member inside the substrate layer. The transformer coil encircles the third magnetic member. The third magnetic member physically separates from the first and second magnetic members.
Claims19
A transformer device comprising:
- a first magnetic member;
- a second magnetic member;
- a substrate layer between the first and second magnetic members, the substrate layer comprising a transformer coil, the transformer coil including an edge exposed on a surface of the substrate layer, the edge electrically coupled to a lead of the transformer device via a bond wire;
- and
- a third magnetic member inside the substrate layer, the transformer coil encircling the third magnetic member, the third magnetic member physically separate from the first and second magnetic members, wherein a first surface of the third magnetic member is coplanar with a first surface of the substrate layer, and wherein a second surface of the third magnetic member is not coplanar with a second surface of the substrate layer;
- and wherein an insulation material in an orifice of the substrate layer contacts the third magnetic member.
