Abstract
An integrated circuit includes a semiconductor die including one or more switching circuits, a magnetic core having length and width, first and second metallic leads, and integrated circuit packaging material. The first metallic lead forms a first winding turn around a portion of the magnetic core, and the first metallic lead is electrically coupled to the semiconductor die. The second metallic lead forms a second winding turn around a portion of the magnetic core. The first and second winding turns are offset from each other along both of the width and length of the magnetic core. The integrated circuit is, for example, included in an integrated electronic assembly.
