Intersil’s Single-Phase Core Controller Powers Intel’s Santa Rosa GPUs

October 11, 2006 by Jeff Shepard

Intersil Corp. introduced the ISL6263A single-phase core controller. This device reduces power consumption and enhances the performance of graphics processing units (GPUs) or graphics cores for Intel Santa Rosa computing products. The ISL6263A dynamically changes the output voltage and operation modes corresponding to the GPU control protocol. Intersil's Robust Ripple Regulator, R³ Technology™ stabilizes current flow and allows less time between wave peaks in a regulator circuit.

"The ISL6263A expands Intersil's portfolio to meet the needs of the latest GPUs requiring dynamic response with VID change on the fly," said Majid Kafi, Director of Intersil's Notebook Power Products Group. "Our PMON feature improves overall battery life and meets and exceeds Santa Rosa specifications. With the family of core power controllers that we have introduced within the last few weeks, Intersil has complete power solutions for both CPUs and GPUs on Santa Rosa as well as Napa platforms."

Intersil's ISL6263A 5-bit VID (voltage identification) controller provides 0.5% system accuracy over the entire temperature range, which allows wider tolerance of inductors for platforms using DCR current sensing. To boost battery life, the controller has the flexibility to go to lower switching frequency at DCM either through internal automatic inductor current sensing or programmed by VID.

Among the ISL6263A's target applications are notebook computer systems, SAN (storage-area network) or NAS (network-attached storage) systems, Point-of-Sale (POS) terminals, and blade servers powered with Intel's Core Duo or Core 2 Duo. The ISL6263A is available now in a 32-lead Thin QFN package and is priced at $3.80 in 1,000-unit quantities.
