Abstract
A power converter includes a power train with a coupled inductor and a plurality of regulators, and method of forming and operating the same. In one embodiment, the power train includes a coupled inductor including a magnetic core with a common leg, a first leg and a second leg. The coupled inductor also includes a common winding formed around the common leg, and first and second windings. The first winding is formed around the first leg, and is electrically and magnetically coupled to the common winding. The second winding is formed around the second leg, and is electrically and magnetically coupled to the common winding. The power train also includes a first regulator including a first main switch coupled to the first winding and a second regulator including a second main switch coupled to the second winding.
