Intersil's Endura Current Sharing Technology Dominates Next-Generation Computer Market

— Endura power management circuits deliver power to over 50 percent of next-generation microprocessors

Irvine, CA, May 24, 2001 - Intersil Corporation (NASDAQ: ISIL), a leading provider of power management solutions for PCs, file servers and portable information appliances, today announced that Intersil's Endura™ current sharing technology will power over 50 percent of Intel® Pentium® 4 processors. Intersil provides the highest performance and the most cost effective multiphase DC/DC converter for Intel's Pentium 4 processor. Nine of the top ten domestic computer original equipment manufacturers (OEMs), as well as Taiwan's first- and second-tier customers, have selected Intersil's Endura HIP6300 and HIP6600A-series power management chipsets for next-generation Pentium 4 designs.

"Intersil's Endura multiphase chipsets will continue to dominate the market by being designed into over 50 percent of the motherboard models featuring next-generation Pentium 4 processors," said Rick Furtney, vice president and general manager of Intersil's Power Management product-line. "The quality, performance, ease-of-use, and reliability of Endura multiphase devices enable computer OEMs, motherboard manufacturers, and voltage regulator module suppliers to transition from concept to production in record time. Our multiphase chipsets arm customers with the ability to develop an easily reproduced Pentium 4 CPU DC/DC converter, a key factor for volume shipments of next-generation motherboards."

Intersil's Endura multiphase devices feature a high level of integration and proprietary architecture offering several system-design advantages. Intersil's innovative rDS(ON) sensing topology, coupled with other architectural features, enhances the converter's efficiency, improves transient response, and reduces overall bill-of-materials cost by eliminating the need for an external current sense resistor. The industry's most precise channel-to-channel current balance further reduces cost by eliminating the need for the over-design of each converter channel. Sophisticated features, such as the controller's ability to automatically reconfigure clock frequency based on the number of populated phases sensed, offers designers the flexibility of designing for a three- or four-phase Pentium 4 DC/DC converter with the same power IC.

Endura devices allow for easy duplication of designs and layouts from one Pentium 4 motherboard model to another, dramatically reducing time to market and helping establish the Pentium 4 as a high-volume, mainstream processor.
