It is the latest member of the BMR491 range which delivers a nominal 24V output from a 40 to 60V input at a power level of up to 1300W.

Output voltage is nominally 24V but a control adjustment via its four-pin PMBus digital interface allows this to be set from 16 to 26.4V nominally, but it can be further adjusted down to 0V if needed. This wide adjustment range enables it to support battery management in remote radio basestation installations and any other applications where conversion from 48V to 24V is necessary at high power levels.

The BMR4912510/871 has a small form factor of 58.4 x 36.8 x 14mm and is 97.1% efficient (for a 54V input voltage at half-load). These dimensions make it suitable for space-constrained applications where thermal management can be a concern, advises the company.

Operating temperature is -40 to 125°C. The quarter-brick DC/DC converter provides 1500V input-output basic isolation for compliance with IEC/EN/UL 62368-1. It also protects against over-temperature, input under-voltage and output over-voltage, over-current and short circuits.

The converter is supported by the company’s Flex Power Designer software for remote configuration, control, and monitoring.

All variants are available in OEM quantities.
