Power module suits suits MicroTCA standard

The ROA 117 5078/1 is a high-density, high-efficiency power module using DC/DC conversion based on synchronous rectification.

Ericsson Power Modules has introduced the ROA 117 5078/1 evaluative level MicroTCA power module.

Aimed at telecom equipment manufacturers (TEMs) and system integrators, the module is for use in systems based on the MicroTCA open-architecture standard.

The ROA 117 5078/1 is a high-density, high-efficiency power module using DC/DC conversion based on synchronous rectification and an FPGA-based enhanced module management controller (EMMC).

The 355W output power rated module features a -48V DC input, 16 channels of 12V payload power and 16 channels of 3.3V management power in a full-size (4.5kW) single-width form factor package.

Offering reduced energy consumption, lower cost of operation, and a lower environmental impact, the modules feature high efficiency, typically 95% at half load.

The module's single-board design offers a cost efficient solution and good thermal performance.

The module is designed to meet the PICMG specification MTCA.0 R1.0, and is intended for interoperability testing with other MicroTCA system components.

It is suitable for use by system integrators and telecom equipment manufacturers during evaluation and testing of MicroTCA-based systems.

The modules' design will be enhanced based on user feedback during the fall of 2007, and it will reach general availability in Q1 2008.

Designs for other input sources and enhanced power levels will also be considered during this process.

Open-architecture platforms such as MicroTCA, supported by commercial off the shelf (COTS) products, allow TEMs to reduce their investment in proprietary hardware, which will shorten design cycles and provide economy of scale by reusing common building blocks.

This supports the ongoing trend amongst TEMs to shift the value added focus from hardware over to applications and services.
