Patent ID: 7864016

Claim:
A two phase coupled inductor for magnetically coupling first and second phases of a power converter, comprising: a rectangular-shaped magnetic core having a bottom planar surface opposite a top surface, the magnetic core forming a passageway extending from the top surface to the bottom planar surface, the magnetic core including a first leg opposite a second leg, the first leg including a first planar surface and the second leg including a second planar surface opposite of the first planar surface, the first and second planar surfaces partially defining the passageway; a first winding having rectangular cross section providing electrical interface for the first phase; and a second winding having rectangular cross section providing electrical interface for the second phase; the first winding being wound about the first leg of magnetic core and through the passageway, the second winding being wound about the second leg of magnetic core and through the passageway, the second winding being separated from the first winding throughout the passageway by a linear separation distance in a plane parallel to the first and second planar surfaces, and the first and second windings each having two ends, each end forming a tab having a planar surface for connecting the end to a printed circuit board, the planar surface of the tab being about parallel to the bottom planar surface of the magnetic core, at least two of the tabs being partially disposed along the bottom planar surface of the magnetic core.
