Industry-first 240-W 1/8-brick module has digital interface

The BMR454 1/8-brick dc/dc converter module delivers up to 240 W with a 95% efficiency rating at 53-V input and 12-V output at full load of 20 A. It has an industry-first PMBus interface to help monitor and adjust converter parameters.

The module can be used as an intermediate bus converter (IBC) in front of a range of regulators, or as a traditional dc/dc module powering applications such as hard-disk drives, fans, and 48-V applications including radio base stations, servers, and routers. It has an input voltage range of 36 to 75 V and an output voltage that can be adjusted between 8.1 to 13.2 V with an output tolerance of ±2%.

The converter module offers a power density figure of 117 W/in.2 and features a 1,500Vdc input-to-output isolation figure. The module is also offered without the PMBus connector, providing the same footprint as a traditional IBC. Three versions of the module are currently available. The BMR4540100/002 is rated at 9 V/20 A, the BMR4540000/001 is rated at 12 V/20 A, and the BMR4540001/001 is also rated at 12 V/20 A, but lacks a digital interface. ($37 ea/10,000 available now.)
