Abstract
A magnetic component and a method for manufacturing a low profile, magnetic component. The method comprises the steps of providing at least one sheet, coupling at least a portion of at least one winding to the at least one sheet, and laminating the at least one sheet with at least a portion of the at least one winding. The magnetic component comprises at least one sheet and at least a portion of at least one winding coupled to the at least one sheet, wherein the at least one sheet is laminated to at least a portion of the at least one winding. The winding may comprise a clip, a preformed coil, a stamped conductive foil, or an etched trace using chemical or laser etching. The sheet may comprise any material capable of being laminated and/or rolled, including, but not limited to, flexible magnetic powder sheets.

30. A method of manufacturing a magnetic component including a coil winding in a magnetic core structure, the method comprising:
-
stacking a plurality of substantially planar and flexible magnetic powder sheets; locating the coil winding between at least two of the stacked magnetic powder sheets; and pressure laminating the flexible magnetic powder sheets around the coil winding to define a magnetic core containing the winding; wherein the sheets are flexed over the coil winding and no physical gap is created in the magnetic core. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38)
