The majority of existing Advanced Telecom Computing Architecture (ATCA) bus convertors employ a combination of front-end interface and conversion module, consuming valuable board space. The new Artesyn dual-input ATC210 bus convertor is a fully integrated solution that occupies 20-40% less space than competing solutions.

It combines an exceptionally small footprint, high power density isolated DC/DC convertor with advanced digitally programmable power management functions.

The convertor has a 5.9 x 4.6cm footprint and a typical full load efficiency of 89%, yielding a power density in excess of 4W/cm3.

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

According to Mark Rice, Vice President of DC/DC Marketing for Emerson Network Power: ‘Many major telecomms companies have come to regard ATCA as the best means of meeting future systems requirements’.

‘It is an open standard architecture, which provides an ideal path away from expensive proprietary platforms’.

‘From a power perspective, the market could become significant - and each ATCA system can contain up to 14 blades, each of which will require at least one bus convertor’.

The ATC210 bus convertor is rated at 210W.

It has dual inputs, each capable of accommodating a very wide input voltage range of -36 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 3.13 to 3.47V.

The convertor is equipped with I2C 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.

Artesyn ATC210 bus convertors are designed specifically for high availability telecomms applications.

Based on a thermally efficient open-frame design, they have an ambient operating temperature range of -25 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 convertors 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 (TUV Product Service) and UL/cUL60950-1 safety approvals, and are Pb-free (RoHS 6/6 compliant) products.

Sample ATC210 bus convertors are available now.

Pricing in 1000-piece quantities is US $148, and the standard lead-time is stock to 8 weeks.
