    Pick the right inductor construction for a desktop-CPU voltage regulator

    Pick the right inductor construction for a desktop-CPU voltage regulator
    Choosing the best inductor construction for desktop-CPU voltage regulators requires a good understanding of inductors and regulators.
    By John Gallagher, Pulse Inc. -- EDN, 4/27/2006
    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.

    Very interesting read, keeping my venerable Epox 9NDA3+ in mind through that entire article brings up a thought or two about the design they employed... Too bad a redesigned voltage drop circuit would be necessary for the ferrite core power cube inductors...
