Intersil Announces Power Management Solutions for Intel Centrino Mobile Technology Platforms; High-Efficiency PWM Controllers Power Intel Pentium M Processor for Extended Battery Life

MILPITAS, Calif.--(BUSINESS WIRE)--March 18, 2003--Intersil Corporation (Nasdaq:ISIL), a world leader in the design and manufacture of high performance analog and wireless networking solutions, today announced the new Endura(TM) ISL6216 and ISL6217 multiphase PWM controllers designed to provide precision core power regulation for the Intel(R) Pentium(R) M processor used in the Intel(R) Centrino(TM) mobile technology platforms for notebook PCs.

The ISL6216 multiphase PWM controller, combined with external MOSFET drivers such as Intersil's ISL6207, offers design flexibility with up to 2-phases of core power current sharing. The ISL6217 two-phase PWM controller integrates two MOSFET drivers, reducing external component count and conserving board space and cost. In addition to core power regulation solutions, Intersil also provides high efficiency PWM controllers for the Intel Centrino mobile technology platform memory, interface control hub chip set and DDR SDRAM.

"Intersil is the only vendor to offer two alternative precision core regulation solutions for the Intel Pentium M processor. The ISL6216 and ISL6217 PWM controllers offer engineers selection and flexibility in their design approach," said Rick Furtney, vice president and general manager of Intersil's High Performance Analog Product Group. "We have secured design-wins with both controllers and are well positioned to support the release and production ramp of notebooks based on the Intel Centrino mobile technology platform."

"Notebook manufacturers have demonstrated battery run times of over 5 hours when running Intel Pentium M processor-based platforms using Intersil's power management solutions," said Dean Henderson, director for Intersil's Portable Power Management Products. "These new platforms will significantly enhance the freedom of mobility for end users."
