BMR492 series

1100 W quarter brick digital isolated DC/DC converter for datacom applications

The BMR492 is the latest generation of our digitally controlled Advanced Bus Converter packaged in an eighth-brick format.

There will be three initial versions, each with an input voltage range of 40 to 60V which meets the typical voltage requirements used in the data center environment.

The first version, the BMR4920302/861 has a continuous output power of 600 W / 50 A, and delivers a fully regulated output of 12 V, adjustable from 8-13.2 V via PMBus.

Isolation between input and output is 1500Vdc, and it boasts a typical efficiency of up to 96.7% at 48Vin / 50% load.

Soon to be released versions will also include a 10.4 V / 700 W continuous output power version capable of supplying up to 950 W of peak power for short durations (1s), and a 12 V / 800 W continuous output power version that can deliver up to 1100 W of peak power. These 2 versions employ Hybrid Regulated Ratio technology to achieve these exceptional levels of power density by boosting the efficiency levels up to 97.4%.

The BMR492 series has an operating temperature range from -40°C up to +125°C and has a mean time between failure (MTBF) of over 6 million hours.

Standard features for the BMR492 include output over voltage protection, output short-circuit protection, over temperature protection, and a digital interface using the PMBus protocol using the 7-pin industry standard.

The BMR492 is supported by our own Flex Power Designer tool.
