Abstract

Two-phase coupled inductors including a magnetic core, at least a first winding, and at least three solder tabs. Power supplies including a printed circuit board, a two-phase coupled inductor affixed to the printed circuit board, and first and second switching circuits affixed to the printed circuit board. Each of the first and second switching circuits are electrically coupled to a respective solder tab of the two-phase coupled inductor affixed to the printed circuit board.
