· Prestigious award from Electronic Products magazine recognizes the ability of the BMR456 and BMR457 DC/DC Advanced Bus Converters to control intermediate bus voltage to deliver high efficiency and significant energy savings
Ericsson has won a 'Product of the Year' award for the company's leading-edge 3E* BMR456 and BMR457 digital power DC/DC Advanced Bus Converters (ABCs) from Electronic Products, a leading trade publication for electronic design engineers. The BMR456 and BMR457 offer unprecedented performance and flexibility to system architects developing equipment for information and communication technologies (ICT) requiring smart and efficient board power solutions.
The 2012 Product of the Year Awards were announced in the January 2013 issue of Electronic Products. The editors of Electronic Products evaluated thousands of products launched in 2012, selecting the winning products on the basis of innovative design, significant advancement in technology or application and substantial achievement in price and performance.
"The BMR456 and BMR457 DC/DC converters are second-generation digital Advanced Bus Converters that set new standards for controlling intermediate bus voltages and maintaining high efficiency," said Paul O'Shea, Senior Editor at Electronic Products Magazine. "Ericsson raised the bar by implementing hardware and firmware to dynamically adjust voltages to meet the requirements of the load conditions. These quarter- and eighth-brick cutting-edge converters will find ready acceptance in the telecom industry."
"We are delighted to win this highly prestigious award from Electronic Products," said Patrick Le Fèvre, Marketing and Communication Director, Ericsson Power Modules. "It is an important industry recognition of the advanced capabilities of the BMR456 and BMR457 converters to dynamically control bus voltages, making it possible to reduce board power consumption from anywhere between 3 and 10 percent, depending on the board application, delivering significant energy savings."
The award from Electronic Products joins other recent award wins gained by Ericsson. Ericsson won the "Green Electronics' category at last month's Electronics Weekly Elektra 2012 awards in London, and earlier in the year, the BMR457 Advanced Bus Converter was named as a top 10 DC/DC power product by Electronic Products China magazine. Ericsson was also nominated as a finalist by UK publication Electronic Product Design in its E-Legacy awards for the company's investment in the environment.

Both of these products feature the 'Ericsson DC/DC Energy Optimizer' firmware - implemented in ARM microprocessor technology - which enables a significant contribution to the reduction of power consumption. Hardware and firmware optimized to meet the demands of the Dynamic Bus Voltage (DBV) power architecture, the output voltage of the quarter-brick BMR456 can be adjusted within an operation range of 13.0V to 8.2V, and with the full benefits of the Ericsson DC/DC Energy Optimizer technology, but furthermore adjusted down to 4V to power ultimate below 5V Sleep Mode configuration, which today requires an extra power-module.
Designed for smaller systems, the eighth-brick-format BMR457 full operational output voltage is optimized to deliver high performance from 13.2V to 8.2V and can be adjusted down to 6.9V making it possible to power the mid-power range of applications requiring 6V Sleep Mode configuration. In both products, the output voltage can be adjusted via PMBus commands or preset profiles stored by the system designer in the built-in USER_STORE memory block, making it simple to adjust the intermediate board bus voltage to a level that will guarantee the lowest power consumption.
In addition, embedding industry-first technology and Ericsson IP, the Ericsson DC/DC Energy Optimizer not only permanently optimizes switching parameters to reduce energy consumption, but also offers a large number of features including the ability to handle input voltage transients with slew-rates up to 0.5 V/µs, while keeping the output voltage within +/-10 percent. This ensures that the output voltage does not trigger over-voltage protection. It also very efficiently manages pre-bias start-up operation and shut down is fully controlled avoiding voltage spikes that cause avalanche conditions in the secondary-side synchronous rectification MOSFET, making a contribution to further improve reliability.
In June 2008, through close cooperation with board and systems designers, Ericsson was the first company to release a 21st century 3E power architecture composed of PMBus-compliant ABCs and POL converters that can be fully integrated into the rest of the digital chain of processors and associated components.
* Enhanced Performance, Energy Management, and End-user Value are the key benefits delivered by Ericsson's range of 3E digitally controlled DC/DC converters.
