Telecom version added to DC-DC converter series

Flex Power Modules has introduced a new version of its BMR480 digital DC-DC converter, optimised for telecom applications that need input voltage down to 36Vin.

The BMR480 0113/034 converter offers an extended input voltage range below 40Vin, as needed for telecom power conversion applications. It is optimised for a wider input voltage range from 36Vin to 60Vin, in comparison to the standard converters in the BMR480 series.

The new version also provides an output voltage of 12V, which is a common demand for telecom and output power up to 800W (output current up to 69A). It offers 1500VDC input-to-output isolation.

Olle Hellgren, director of product management and business development at Flex Power Modules, said: “Telecom applications have specific requirements, and with this new version, we’re delivering what customers in this sector need – while still offering them the proven efficiency, reliability and performance of our existing BMR480 series.”

When compared to other options on the market, the BMR480 telecom version claims to provide higher thermal performance, with efficiency of typically 96.4% at 53V output voltage and half load. Thermal performance is improved by a baseplate, which can be joined to a heatsink or cold plate, and the converter provides an extended operating temperature range of -40C to +125C.

The telecom version is offered in an industry-standard low-profile quarter-brick form factor, measuring 58.4mm x 36.8mm x 14.48mm (2.3" x 1.45" x 0.57").
