48-V-to-processor power conversion solution enables 30 percent reduction in power conversion loss per processor

July 11, 2012 // By Paul Buckley
Vicor Corporation has introduced the company’s first direct 48 V-to-processor power conversion solution for the datacenter, cloud computing and telecom markets.

Vicor’s Factorized Power solution complies with Intel’s x86 VR12.0 voltage regulation specification. Vicor’s current multiplication from 48 V directly to a 1V microprocessor load enables more efficient power distribution and eliminates duplicate conversion stages found in traditional 48 V to 12 V to 1 V power systems, yielding more than 5% greater overall efficiency in a package size that’s 3X smaller than competing offerings.

With increasing demands on datacenter and cloud computing infrastructure, efficient power management is a growing concern. Electricity costs can account for up to 50% of annual datacenter operating expenses. The 5% efficiency gain enabled by Vicor’s Intel compliant power solution can reduce per-processor power loss by 10 W – or 30% – which can yield annual datacenter electricity savings of approximately $500,000 across 30,000 onsite processors.

Vicor’s VI Chip PRM non-isolated regulator and VTM current multiplier deliver the most efficient 48 V direct-to-load power conversion for datacenter and telecom applications. Vicor’s Factorized Power Architecture (FPA) separates, or ‘factorizes’, regulation and voltage transformation functions into flexible, high performance building blocks, reducing distribution and interconnect losses and eliminating bulk capacitance with greater than 1 MHz response speed.
