Ericsson BMR456 & BMR457 DC-DC Advanced Bus Converters (ABC) can reduce board power consumption by 3 to 10%. Both modules have the ability for the output voltage to be adjusted via PMBus commands or the preset profiles. The power modules were awarded the 2012 Product of the Year by Electronic Products Magazine for their ability to control intermediate bus voltage to deliver high efficiency and significant energy savings. BMR456 and BMR457 Advanced Bus Converters from Ericsson can reduce board power consumption by 3 to 10%, depending on the board applications. Both modules feature Ericsson DC-DC Energy Optimizer firmware for power consumption reduction. The quarter-brick BMR456 output voltage can be adjusted within an operation range of 13.0V to 8.2V. The output voltage of the smaller eighth-brick BMR457 delivers 13.2V to 8.2V and can be adjusted down to 6.9V.
