Abstract
A multi-phase integrated power inductor component assembly includes a plurality of conductive windings on an integrated magnetic core structure accepting each of the plurality of conductive windings in a spaced apart, non-coupled arrangement with respect to one another. The integrated magnetic core structure includes a series of magnetic gaps each being respectively centered on one of the plurality of conductive windings. The windings include surface mount terminations for connection to a circuit board.

An inductor component assembly comprising:
- a plurality of conductive windings each comprising a planar main winding section and opposing winding legs extending perpendicularly from the planar main winding section;
- an integrated magnetic core structure accepting each of the plurality of conductive windings in a spaced apart, non-magnetically coupled arrangement with respect to one another;
- wherein the integrated magnetic core structure includes a series of magnetic gaps each being respectively centered on one of the planar main winding sections;
- and
- wherein the ends of the opposing winding legs are turned inwardly on a bottom side wall of the integrated magnetic core structure to define surface mount terminations for connection to a circuit board.
