Intersil Controllers Selected by QDI, China’s Largest Computer Motherboard Manufacturer

— Endura™ Multiphase PWM Controllers to supply power for Legend QDI

IRVINE, CA. — February 7, 2001 — Intersil (NASDAQ: ISIL), a leading provider of power management solutions for PCs, file servers and portable information appliances, announced today that Legend QDI has selected the Intersil Endura™ multiphase power conversion chipset for motherboards that will be used in high-performance desktop personal computers (PCs) using AMD Athlon^® and Intel^® Pentium^® 4 processors. Legend QDI is the largest computer motherboard manufacturer in the People’s Republic of China (PRC).

"Intersil is committed to meeting the increased power demands of high-performance computer systems that are used in high-availability markets requiring 24x7 reliability, such as electronic commerce," said Rick Furtney, vice president and general manager of Intersil’s Power Management business. "Selection by China’s leading motherboard manufacturer reinforces Intersil’s leading market position to satisfy the power requirements of next-generation processors."

Intersil’s Endura modular multiphase converter circuit enables trouble-free scalability in computer power systems. As desktop PCs use newer and faster Central Processing Units (CPUs), newer pulse width modulation (PWM) controllers are required to address the challenge of the increased power requirements. The multiphase synchronous buck controller topology pioneered by Intersil enables the motherboard designer a complete, robust DC/DC solution to supply power to these fast CPUs.

"Legend QDI takes pride in the quality of its products, and all of our motherboards undergo a series of strict quality inspections," said KK Ho, Assistant G.M. of Legend QDI. "With production volumes reaching more than 350,000 motherboards a month, any component failure or small parametric drift can be catastrophic. But Intersil Endura power products have long histories of proven reliability and meeting the exacting standards that our customers expect. As the major motherboard manufacturer in China, we are pleased to have forged a strong relationship with Intersil, which is the world’s leader of desktop computer power products."

About the HIP630X/HIP660X Family
The Intersil HIP630X/HIP660X multiphase product family consists of five multiphase PWM controllers and three MOSFET drivers, and uses a patented circuit topology that yields the highest performance multiphase DC/DC converter while requiring fewer and smaller passive devices. Intersil employs a unique current balance approach between the DC/DC converter phases that guarantees the industry’s most accurate phase-to-phase current balance for microprocessor power supplies.

The HIP6301, HIP6303, and HIP6311 are two–to–four phase PWM controllers that regulate output current above 100A (ampere), whereas the HIP6302 and HIP6304 are dedicated two-phase devices that control microprocessor loads in the 50A range. The HIP6601A and HIP6603A are single-channel MOSFET drivers, while the HIP6602A drives four n-channel MOSFETs in a multiphase buck DC/DC converter.

Chipset and Availability

The HIP6301, HIP6303, and HIP6311 are offered in 20-pin narrow-body SOIC packages.

The HIP6302 and HIP6304 are offered in 16-pin narrow-body SOIC packages.

The HIP6601 and HIP6603 are offered in 8-pin narrow body SOIC, 8-pin TSSOP, and the new, thermally enhanced 8-pin Exposed-Paddle (E-Pad) SOIC and sixteen-pin 4x4 Micro Lead Frame (MLF) packages.

The HIP6602 is offered in fourteen-pin narrow body SOIC and the new, thermally enhanced sixteen-pin 5x5 Micro Lead Frame (MLF) package.
