An embedded magnetic component transformer includes first, second, and auxiliary electrical windings in an insulating substrate including conductive vias joined together by conductive traces. The first electrical windings are divided by a tap terminal into first and second winding portions, which are interleaved with one another and energized by separate transistors. Heat generated by the first and second winding portions is transferred more equally to the separate transistors. Equal or substantially equal path lengths between each of the transistors and the first electrical windings improve flux balance allowing the transistors to conduct for equal or substantially equal times during a switching cycle. Thus, the switching cycle of the embedded transformer is more symmetric with respect to each of the transistors and winding portions, improving the electrical characteristics of the transformer. |
