A power converter employing a magnetic device including a magnetic core and first and second tapped windings. Each winding of the magnetic device has first and second winding sections, respectively, coupled to the magnetic core, wherein the first and second winding sections are formed from a formed and folded planar conductive sheet. The magnetic core includes a common leg, a plurality of outer legs, and a top plate. The first and second winding sections are constructed with a formed and folded planar conductive sheet formed with structures usable as pins in a through-hole, surface-mount, or combined printed wiring board assembly process. The outer legs at either end of the magnetic core are positioned back from magnetic core ends, and the magnetic core is formed with a stepped structure to accommodate winding pins in a surface-mount printed wiring board assembly process.
