Abstract: A low-profile dual-phase inverse coupled inductor structure can include diagonally overlapped windings and gap controlled inverse coupling, such as can be useful to help achieve strong negative coupling and high saturation current for POL applications. The device may include a coupled inductor structure comprising a first magnetic core piece, and a conductive first winding portion on at least a portion of the first magnetic core piece. An electrical insulator may be included on at least a portion of the first winding portion and a conductive second winding portion may be located such as to cover the insulator. At least a portion of the second winding portion overlaps, and may be separated by the insulator from, at least an underlying portion of the first winding portion. A second magnetic core piece may be located on the second winding portion.

Abstract: A device may include a coupled inductor structure comprising a first winding portion, a second winding portion, and a magnetic core structure. The magnetic core structure may include a first and second core piece that are at least partially cross-sectionally U-shaped. A first connecting core piece may be attached to a first portion of the first core piece to a first portion of the second core piece, and a second connecting core piece may attach a second portion of the first core piece to a second portion of the second core piece.
