Vicor V·I Chip Components Reduce Energy Costs

Increase Efficiency and Power Density

Andover, MA, November 13, 2006...Vicor Corporation (NASDAQ: VICR) today announced the availability of a full family of V·I Chip(TM) components, enabling complete power systems using Factorized Power Architecture (FPA). FPA separates or 'factorizes' regulation and voltage transformation functions into flexible, high-performance building blocks. V·I Chip components are high-density (up to 1.2 kW/in3), high-efficiency (up to 97%), high-speed power conversion modules, and are all released for mass production.

The PRMTM (non-isolated regulator) and VTMTM (current multiplier) components deliver the most efficient 48 V direct-to-load power conversion system in mass production today. For low voltage/high current requirements (e.g. microprocessors), the VTM module enables 91 A/in2 point of load (POL) density. FPA allows the PRM module to be deployed remotely, providing greater design flexibility and a 95% reduction in distribution loss.

Stephen Oliver, Vice President of Marketing & Sales for the V·I Chip Division, says: "As energy prices increase, the electricity bill for a data center is now 50% of the annual operating cost-growing to more than the initial hardware investment-and it takes 2.6 W to drive 1 W of computing power in a typical system. A data center using an FPA solution could save 24 Euros or $30 per processor, per year in energy costs. At the same time, the power solution with VoI Chip modules is 45% smaller, enabling further increases in computing rack density."

Vicor's PRM and VTM modules cover a wide range of input and output voltages at power densities up to 1.2 kW/in3 or 100 A per module. FPA solutions are available to meet the advanced requirements of telecom/server (processor and memory power supply), test equipment, RF amplifiers, power supplies, and many other applications.

In traditional 48 V architectures, Vicor's intermediate bus converters, the BCMTM modules, offer four times more power density than any other converter. The 48 V BCM modules are available with output voltages of 1.5 Vout to 48 Vout and up to 300 W and are suitable for telecom/server, base stations, WiFi, data/voice, VoIP (Voice over Internet Protocol), and PoE (Power over Ethernet), as well as solid-state LED lighting, lasers, and broadcast equipment.

In addition, Vicor's high-voltage (350 - 380 Vin) BCM converters provide efficient high-voltage distribution and post-PFC high voltage DC-DC conversion to non-isolated POL converters in telecom and high-end server systems.

The VoI Chip family is in mass production now with immediate sample availability and four-week production leadtimes. A VoI Chip PRM + VTM chipset to convert from 48 V direct to 1 V, 100 A is available for $49 in OEM quantities. BCM converters are available from $32.50 each in OEM quantities.
