Until recently, cost and the ability of a part to function in an application have driven the choice of inductors in desktop-computing systems' processor-voltage regulators. Designers have not been greatly concerned with component size, parameter tolerance, or performance requirements. As a result, inductor design for these systems lagged behind the state of the art. Over the past three years, however, the industry has begun to awaken, and vendors have proposed and evaluated several new inductor platforms to overcome new challenges resulting from changing regulator requirements.
