Abstract
An integrated inductor assembly includes a magnetic core including a center leg in parallel with a first outer leg and a second outer leg on either side of the center leg. A first set of windings of a first inductor are wrapped around the center leg, the first outer leg of the magnetic core, and the second outer leg of the magnetic core. A second set of windings of a second inductor are also wrapped around the center leg, the first outer leg, and the second outer leg of the magnetic core. The first set of windings and the second set of windings include center windings wrapped around the center leg of the magnetic core, first outer windings wrapped around the first outer leg of the magnetic core, and second outer windings wrapped around the second outer leg of the magnetic core.
