EL SEGUNDO, CA, May 1998 - International Rectifier (IR), the power experts, now offer an application-specific power chip set that exceeds Intel's Mobile Power Guideline 1999 standard for notebook PC power supplies. This new pair of low-voltage HEXFET^®power MOSFETs designated the IRF7805 and IRF7807-- sets a new standard for efficiency in low voltage DC/DC converters, reducing losses by 20 percent in Pentium II microprocessor DC/DC converters and improving overall notebook power supply efficiency to 92 percent.

"In the past, power MOSFET have concentrated on developing and promoting leading edge MOSFET technologies -- 'planar', 'trench', 'stripe', etc. -- in effect forgetting what the customer needs," said Chris Ambarian, director of marketing for MOSFETs and IGBTs at IR. "With our new HEXFET chip set, we have taken a more customer-centric approach to meeting the higher power efficiencies required in advanced electronic products," he continued. "Using our in-depth knowledge of the DC/DC converter application, we chose the most appropriate silicon technologies to develop MOSFETs with the best overall performance within a very specific power supply system. We believe that the new chip set represents the best use yet use of an application specific approach to problem solving in the power MOSFET arena," he indicated.

"In the MOSFET market of the future, buzz words and specsmanship simply can't help our customers choose the right power conversion solution," Ambarian added. "That's why we are providing new data sheets on our application-specific developments that provide information directly related to actual operating conditions in the application, for example. Successful MOSFET suppliers will have to better understand the applications for their products, and partner with customers to develop the best possible power conversion component solution for that application.

"These portable power devices are just the beginning," Ambarian indicated. "We will be introducing a number of application-specific power solutions in coming months in the areas of off-line power supplies and DC/DC converters, as well as automotive and telecommunications applications. It's a whole new ball game."
