Abstract
Embodiments disclosed herein include power transformers for microelectronic devices. In an embodiment, a power transformer comprises a magnetic core that is a closed loop with an inner dimension and an outer dimension, and a primary winding around the magnetic core. In an embodiment, the primary winding has a first number of first turns connected in series around the magnetic core. In an embodiment, a secondary winding is around the magnetic core, and the secondary winding has a second number of second turns around the magnetic core. In an embodiment, individual ones of the second turns comprise a plurality of secondary segments connected in parallel.
