Fairchild mit neuem Spannungsregler für AMD CPU's

Fairchild Semiconductor haben den neuen Spannungsregler FAN5098 für Hammer Prozessoren vorgestellt. Dadurch wurde wieder ein Stück im K8 Puzzle bekannt; die Betriebsspannung von AMD's Neuling wird je nach Modell zwischen 0,80 und 1,55 Volt liegen.

November 6, 2002?San Jose, Calif.? Fairchild Semiconductor International (NYSE: FCS) announces the FAN5098 DC/DC Voltage Regulator IC for the upcoming AMD Opteron? and AMD Athlon? processors with Hammer technology. The FAN5098 is intended for use in providing precise, efficient power regulation for the CPU VCORE in desktop, workstation and server applications. The FAN5098 uses a multi-phase architecture, including unique control-loop methods to improve load regulation and transient response, specifically addressing the requirements of advanced microprocessors.

"Fairchild collaborated with AMD to develop the FAN5098, which provides a cost-effective, complete solution while meeting all requirements of AMD processors with Hammer technology," said Abid Hussain, Product Marketing Manager, Fairchild Semiconductor.
The two-phase FAN5098 includes built-in, high-performance MOSFET drivers for the highest integration available in the industry. 5-bit VID codes allow for output voltages from 0.800V to 1.550V. Dynamic VID transitions are supported per AMD specifications with glitch-free output voltage and controlled slew-rate. Typical output current is 42A and is easily scalable, thus enabling flexible motherboard designs to support future AMD processors. Current sensing is achieved with loss-less MOSFET RDS(on) methods and current matching is closely controlled between the output phases.

"The new Fairchild FAN5098 voltage regulator provides efficient, power regulation for the CPU VCORE in AMD solutions," said Ed Gasiorowski, director of the AMD Infrastructure Enablement Group. "Shared AMD and Fairchild customers will benefit from stable, reliable solutions."

Der neue Chip kostet bei einer Abnahme von 1000 Stück 1,88$ und ist ab sofort verfügbar.
