1. A planar transformer comprising:
a printed circuit board having a first layer and a second layer proximate the first layer;
a first planar winding disposed within said first layer of the printed circuit board;
a second planar winding disposed within said second layer of the printed circuit board;
a magnetic material disposed unitary and integral within said printed circuit board material, wherein the magnetic material comprises magnetic thermoplastic laminate material; and
a magnetic core disposed over and through the printed circuit board and magnetically coupled to the first planar winding and the second planar winding.
