Flex Power Modules BMR456 & BMR457 DC-DC Bus Converters

Flex Power Modules BMR456 and 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 have the ability to control intermediate bus voltage to deliver high efficiency and significant energy savings. Flex BMR456 and BMR457 Advanced Bus Converters can reduce board power consumption up to 10%, depending on the board applications. Both modules feature 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.
