Ericsson has unveiled the first model in its second generation of digital Advanced Bus Converter (ABC) products. Based upon the FRIDA II platform, which was announced earlier this year, the Ericsson BMR456 3E* Advanced Bus Converter is designed for 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 company says.
This new generation of fully regulated digital DC/DC converters is based on a 32-bit ARM microcontroller that embeds the family’s most advanced firmware to date. The FRIDA II firmware was 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.
Designed to power telecom and datacom applications, the BRM456 is available in two input voltages ranges: 36V to 75V, delivering output power of 420W; and 40V to 60V, delivering output power up to 468W. Output voltage can be adjusted across a range from 4.0V to 13.2V 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.
