The Ericsson BMR456 3E Advanced Bus Converter claims to deliver unprecedented performance to system architects who are developing equipment for ICT (Information and Communication Technology) applications that require fast response time, tightly regulated intermediate bus voltages and high efficiency at any point of operation to reduce power consumption.

The new generation of fully regulated digital DC/DC converters is based on a 32-bit ARM microcontroller that embeds the familys most advanced firmware to date. The FRIDA II firmware has been developed by Ericsson to guarantee the highest possible performance at any point of operation from low load to high load, and to handle line transients, such as those occurring in ATCA (Advanced Telecommunications Computing Architecture) applications when, for example, switching from Feed A to Feed B.

Patrick Le Fvre, Marketing and Communication Director, Ericsson Power Modules, commented: The BMR456 is the first product to be based on the FRIDA II platform and firmware and is the culmination of technology innovation that demonstrates Ericssons firm commitment to reduce energy consumption.

Designed to power telecom and datacom applications, the BRM456 is available in two input voltages ranges: 36 V to 75 V, delivering output power of 420 W; and 40 V to 60 V, delivering output power up to 468 W. Output voltage can be adjusted across a range from 4.0 V to 13.2 V via PMBus commands, making the BMR456 suitable for Dynamic Bus Voltage operation resulting in the reduction of energy consumption when communication data traffic is low.
