Patent ID: 7482905

Claim:
A power converter, comprising: an energy transfer element including a primary port and a secondary port; and a switched circuit coupled to either the primary port or the secondary port to regulate an output characteristic of the power converter, wherein the energy transfer element further includes: a single magnetic element including an external surface; first and second electrically conductive pins attached to the single magnetic element; a first winding wound around the single magnetic element directly around the external surface of the single magnetic element without a bobbin, the first winding having first and second ends coupled to the first and second conductive pins, respectively, the first winding magnetically coupled to the single magnetic element; and a second winding wound around the single magnetic element directly over the first winding, the second winding having first and second ends not coupled to electrically conductive pins attached to the single magnetic element, the second winding magnetically coupled to the single magnetic element such that energy to be received from the primary port is to be transferred from the first winding to the second winding through the magnetic coupling provided by the single magnetic element to the secondary port.
