iWatt and E&E Magnetics Enter Agreement to Promote Patented IKOR® Coupled Inductor Technology

Business Wire, June 11, 2007

The companies will work together to bring power delivery solutions to customers desiring high efficiency, low component count and small size

LOS GATOS, Calif. -- iWatt, Inc., a leader in digital power conversion IC technology and E&E Magnetic Products Ltd., a major supplier of magnetic products to the global market, announced that they will be working together to bring high-efficiency coupled inductor solutions to high performance applications such as servers. The combination of iWatt's propriety coupled inductor technology and E&E's high volume manufacturing capability will provide high-performance power solutions that save space, reduce cost and maximize efficiency while still meeting tough CPU voltage regulation requirements.

"IKOR Coupled inductor technology promises to bring the next level of cost and space savings to voltage regulators for CPU and other high-performance point-of-load applications," said Doyle Slack, Vice-President of Marketing at iWatt. "We are very excited to be joining forces with E&E to help us to promote our technology."

"The E&E management is pleased to partner with iWatt in promoting IKOR coupled inductor technology to our global customers," said Mark Saxon, Vice-President of Marketing at E&E. "The combination of both iWatt and E&E's technical expertise and manufacturing capabilities will provide optimum solutions to the power industry."

As part of the agreement, iWatt and E&E will work together on reference designs and provide design-in support to customers for their high-performance VR designs. E&E will sell inductors to customers worldwide. The purchase of these inductors will grant end-users a per-use license to use the patented IKOR technology in their end products.

About Coupled Inductor Technology

The IKOR coupled inductor technology solves the most pressing problems facing low voltage, high current VRM and VRD designs by removing the first order limit on output inductance. IKOR coupled inductor technology makes it possible to radically reduce VRM output inductance without increasing switching frequency. Operating at this lower frequency keeps efficiency high while still allowing for the use of a small amount of MLCC-only output capacitance. This eliminates the need for expensive and unreliable bulk electrolytic capacitors. Another feature of this technology is that it is equivalent in transient response performance to higher frequency solutions due to the coupling between phases.

In summary, the key features of IKOR coupled inductor technology are:

-- Significant reduction of output capacitor size / cost

-- Simultaneously delivers:

    -- High efficiency

    -- Elimination of bulk electrolytic and POS-Caps

    -- Fast transient response (due to low output inductance)

-- Each phase controls full output current

-- Symmetrical transient response for up & down current step
