Patent ID: 8416043

Claim:
A coupled inductor, comprising: a monolithic magnetic core formed of a powder magnetic material; first, second, third, and fourth terminals; a first winding at least partially embedded in the monolithic magnetic core, the first winding electrically coupled between the first and second terminals; and a second winding at least partially embedded in the monolithic magnetic core, the second winding electrically coupled between the third and fourth terminals, the second winding at least partially physically separated from the first winding within the monolithic magnetic core; wherein: the powder magnetic material comprises a moldable binder, the second and fourth terminals are part of a common terminal, the first and third terminals are disposed proximate to a first side of the monolithic magnetic core, and the common terminal is disposed proximate to a second side of the monolithic magnetic core, the second side being opposite to the first side, and the first and second windings are configured such than an electric current flowing through the first winding from the first terminal to the common terminal induces an electric current flowing through the second winding from the third terminal to the common terminal.
