Ericsson Power Modules BMR454: 240W one-eighth-brick module provides digital interface

Allowing monitoring using a PMBus interface, the BMT454 eighth-brick family delivers 240W and a 36 to 75V input-voltage range. The devices are 95%-efficient at 53V input and 12V output at 20A full loads. They target information- and communication-technology applications requiring 48V power. These applications include radio base stations, servers, and routers. The devices also suit use as an intermediate-bus converters with regulators or as dc/dc modules powering hard drives and fans. The modules feature a 1500V dc input-to-output isolation figure, allow output-voltage adjustments between 8.1 and 13.2V with a ±2% output tolerance, and have 18W/cm² power density. Available in 9V/20A, 12V/20A, and 12V/2A models without a digital interface, the BMR454 costs $37 (10,000).
