Flex Power Modules: new series of digital eighth-brick DC/DC convertersERT

Flex Power Modules announced BMR492 – a series of digital eighth-brick intermediate bus converters capable of delivering between 600 to 800W of continuous power along with a peak power of up to 1100 W for short periods <1s.

The new BMR4920302/861 converter, the first of three variants of the BMR492 family to be introduced, delivers a 12V output. Rated to a maximum 600W output over an input voltage range of between 40-60V, the DC/DC step-down solution is ideal for nominal 48 or 54 V input voltage systems commonly found in data center server applications.

The through-hole mounted device is fully regulated and includes an input to isolation voltage of 1500Vdc.

This BMR492 variant delivers an extremely efficient operation evidenced by a peak efficiency of 96.7% at 48 Vin at half load. The output voltage is pre-programmed at 12 V as standard, but this can be adjusted across a wide range of 8 to 13.2 V via the incorporated PMBus interface.

This feature is also useful to optimize system level efficiencies through dynamic bus voltage adjustment according to the supplied load.
