Intersil's Single-Phase Core Controller Powers Intel's Santa Rosa GPUs
— Intersil's ISL6263A Uses Patented R3 Technology™ to Deliver the Industry’s Best Transient Response for Graphics Processing Units (GPUs) or Graphic Cores for Intel's Santa Rosa Platform
MILPITAS, CA, October 10, 2006 – Intersil Corporation (NASDAQ Global Select: ISIL), a world leader in the design and manufacture of high-performance analog
semiconductors, today 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."
Faster Transient Response, Improved Efficiency
Intersil’s
ISL6263A 5-bit VID (voltage identification) controller provides 0.5
percent 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.
Compared with traditional single-phase core controllers, Intersil’s R3-based
controller provides better transient response and light-load efficiency and is
capable of changing the voltage output when the GPU is in suspend or sleep mode.
It reports the GPU power consumption through a highly accurate continuous analog
output signal.
