Intersil is working with AMD to provide advanced multiphase power solutions for the upcoming AMD Opteron and AMD Athlon processors.

Intersil's advanced power solutions provide cost effectiveness, reliability and high efficiency.

"The upcoming AMD Opteron and Athlon processor-based platforms are poised to meet future 64bit market needs with exceptional technology and performance.

Intersil's advanced core power management solutions will help ensure reliability and high operating efficiency for consumers as well as enterprise computing", said Rick Furtney, vice president and general manager of Intersil's High Performance Analogue Product Group.

"AMD and Intersil customers will have scalable, flexible solutions that can grow with the customers' needs".

"The upcoming AMD processors and Intersil's CPU power management solutions will ensure that system components, including graphics cards, I/O and DDR memory, provide optimised 32 and 64bit performance", said Rich Heye, vice president platform engineering and infrastructure.

"Demanding consumer and enterprise customers can use the upcoming AMD and Intersil technologies to increase computing performance in single and multi-processor environments".

The Intersil Endura solution to power AMD's next-generation processors is based on the new two-phase ISL6569 and four-phase ISL6559 PWM controllers.

These robust controllers work with any of Intersil's mosfet drivers such as the single-channel HIP6601B, HIP6603B and HIP6604B and dual-channel HIP6602B.

The ISL6569 is offered in a 24-lead SOIC or 32-pad 5 x 5mm micro lead frame plastic (MLFP) package while the ISL6559 is offered in a 28-lead SOIC or 32-pad 5 x 5mm micro lead frame plastic (MLFP) package.

Both the ISL6569 and ISL6559 are loaded with features that provide protection, precision and high converter efficiency.

Notable features include: precise differential remote output voltage sensing, Dynamic VIDT technology for "on-the-fly" VID changing, 5 or 12V bias and a pin-adjustable reference offset.

These devices also use mosfet on-resistance for current sensing to save space and component costs.

Evaluation platforms and complete reference designs are available now to assist engineers with solution evaluation and design-in.

The ISL6569 will be available in mass production in May while the ISL6559 will be in production in June.
