Artesyn dual-input ATC210 bus converter from Emerson

Emerson Network Power has announced the Artesyn dual-input ATC210 bus converter, which the company claimed is the smallest front-end power solution to date for use on the latest-generation telecoms cards. The majority of existing Advanced Telecom Computing Architecture (ATCA) bus converters employ a combination of front-end interface and conversion module, consuming valuable board space.

The Artesyn dual-input ATC210 bus converter is a fully integrated solution that occupies 20 percent to 40 percent less space than competitive solutions. It combines small footprint and high power density, isolated DC/DC converter with advanced digitally programmable power management functions. The converter has a 5.9-by-4.6cm footprint and a typical full load efficiency of 89 percent, yielding a power density in excess of 4W/cm3.

The ATC210 is expressly designed for use in ATCA systems, and is a suitable design choice for many other space-constrained systems that employ distributed power architectures.

"Many major telecoms companies have come to regard ATCA as the best means of meeting future systems requirements," said Mark Rice, VP of DC/DC marketing at Emerson Network Power. "It is an open standard architecture, which provides an ideal path away from expensive proprietary platforms. From a power perspective, the market could become significantand each ATCA system can contain up to 14 blades, each of which will require at least one bus converter."

-36V to 72V input range
The ATC210 bus converter is rated at 210W. It has dual inputs, each capable of accommodating a wide input voltage range of -36V to 72V and generates two independent, isolated DC outputs. The main 12V output can deliver up to 17.5A and is intended for powering an on-card intermediate bus. The secondary output is for supplying peripheral power management circuitry, it is rated at 1.8A and is resistor programmable over the range 3.13V to 3.47V. The converter is equipped with I?C serial bus and direct high-speed interfaces for monitoring, reporting and digital programming of fault thresholds. Built-in power management functions include input ORing, inrush control and transient protection.

The ATC210 bus converters are designed specifically for high availability telecoms applications. Based on a thermally efficient open-frame design, they have an ambient operating temperature range of -25C to 85C and employ conservative derating criteria to achieve a typical MTBF in excess of 2 million hours (in accordance with Telcordia SR-332). The converters are comprehensively protected against overload and fault conditions and have a two-year warranty. They meet the rigorous ETS 300 386-1 immunity and emission standards, feature EN60950-1 (T?V Product Service) and UL/cUL60950-1 safety approvals and are Pb-free (RoHS 6/6 compliant) products.

Sample ATC210 bus converters are available today. Pricing in 1,000-piece quantities is $148, and the standard lead-time is stock to eight weeks.
