Celestica Inc.'s voltage-regulator module VRM 9.1 family of dc/dc converters is specifically designed to help computing OEMs meet the system cost and performance challenges associated with next-generation 32-bit processors. The units are said to exceed all the compatibility requirements defined for Intel Xeon processors and Xeon-based platforms.

Simultaneously, the company has also announced its Power Pod dc/dc converters for Intel Itanium 2 processors.

Available in a 96.52-by-58.42-by-14.48mm form factor, the 12V-input VRM 9.1 claims enhancements in current, voltage ID and control output voltage range. Transient response is 50A/ms.

The VRM 9.1 family "delivers high-performance dc/dc solutions for next-generation IA-32 processors," said Christopher Stratas, GM at Celestica Power Systems. "With such a variety of models, the family provides advanced solutions for individual system requirements and supports our goal of providing cost-effective power solutions."

The VRM is available in three versions, one based on standard Intel specifications; a second, low-profile solution utilizing a standard card-edge connector; and a model that is available in a 1U size (in this case, only 31.75mm) for optimal system packaging. Its mechanical dimensions are achieved with soldered-in pin connectors while adhering to Intel-standard electrical specifications.

The Power Pod dc/dc converters for the Itanium 2, meanwhile, run from a 12V input and use an open-frame design that allows for better thermal management in today's system environments. Available in a 124.84-by-22.1-by-70.74mm, the Power Pod is 25.4mm shorter than the industry standard to conserve board real estate for high-density systems. It also fits in a 1U (44.45mm) system.

All converters are available now. VRM 9.1 pricing starts at under $29 for OEM quantities ($47 each in small lots). Power Pod pricing starts at $180 and $275 for the 12V, and 48V models respectively, both in lots of one to 25 units.
