Abstract
A multi-layer and multi-functioning printed circuit board (PCB) defines a magnetic component formed using planar technology and multiple PCBs, each having four or six layers and each including a single winding. One set of windings is configured as an inductor and a second set of windings is configured as a transformer. The PCBs are stacked in an offset arrangement such that pins connecting one set of windings on a PCB or PCBs to a main circuit board do not penetrate the PCB or PCBs including another set of windings. The invention is configured to function both as an inductor and a transformer.
