World-class innovation to reduce environmental impact of electronic equipment

Award winning Eighth-brick-format BMR457 delivers unprecedented performance to system architects developing equipment for ICT (Information Communication Technology) applications

Ericsson is named a winner in the annual Electronic Products China Top Product Awards. The innovative BMR457 32-bit processor-based FRIDA II 3E* digital ABC (Advanced Bus Converter) was named a top 10 DC/DC power product by the magazine. The award is in recognition of the company's world-class expertise in consistently developing innovative and highly efficient products that significantly reduce the environmental impact of electronic equipment. Ericsson has finely honed the efficiency of its R&D activities, implementing a lean and agile R&D methodology. This resulted in shortened feedback loops, improved communication, and rationalised processes, across all the company's product development, including its leading technologies used in digital power modules. "The development of the BMR457 is a result of the extremely close cooperation between Ericsson R&D centers in both Sweden and China, to deliver this leading-edge product in an exceptional fast time frame," said Patrick Le Fèvre, Marketing and Communication director, Ericsson Power Modules. The BMR457 integrates a 32-bit ARM-based digital microcontroller, that embeds the advanced ‘Ericsson DC/DC Energy Optimizer' firmware. This has been developed by Ericsson to guarantee the highest performance at any point of operation from low to high load, which is commonplace when handling data traffic. The ‘Ericsson DC/DC Energy Optimizer' firmware combines advanced Ericsson IP (Intellectual Property) together with a series of industry-first functionalities to continually optimize switching parameters and reduce energy consumption to an absolute minimum. The BMR457 is available in two input voltage ranges: from 36V to 75V, delivering an output power of 264W; and from 40V to 60V, delivering 300W. Output voltage can be adjusted in a range of 6.9V to 13.2V via PMBus commands, making BMR457 suitable for DBV (Dynamic Bus Voltage) operation with its ability to reduce energy consumption when traffic data demand is low. Ericsson was the first company to launch digitally controlled POL (point-of-load) regulators based on a digital core controller. Through close cooperation with board and systems' designers, the company was also the first to release a 21st century power architecture that can be fully integrated into the rest of the digital chain of processors and associated components.
