The device delivers up to 860 W of continuous power at efficiency levels of &gt;98% (measured at half load) in an extremely compact package measuring just 58.4 x 25 x 9.9 mm, which includes an integrated baseplate enabling simplified conduction cooling to the customers&#8217; heatsink or cold plate. Peak power delivery of up to 1000 W is also possible for short durations (&lt;1s).<\/p>\n\n\n\n<p>The input voltage range is 40-60 V which is suitable for 48\/53 V applications such as those found in Data Centers, High Performance Computing and Cloud Computing applications for example, and the unregulated output voltage of 10-15 V makes it suitable to be used to power downstream Point of Load (PoL) converters and integrated power stages such as the <a href=\"\/products\/power-modules\/series\/bmr510\" target=\"_blank\" rel=\"noreferrer noopener\">BMR510<\/a>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-small-font-size\">Key Benefits<\/h3>\n\n\n\n<p>The BMR310 offers additional solutions to Flex Power Modules&#8217; customers when it comes to choosing an IBC for systems transitioning from legacy 12V feeds to a 48V feed. Using capacitive energy transfer with soft-switching of the power devices enables a much smaller footprint and lower height profile, and in addition to the initial version which includes a baseplate measuring just 9.9mm tall, future versions will include an open frame design, significantly reducing the overall height of the IBC still further.<\/p>\n\n\n\n<p>Paralleling of the converters is supported using passive Droop Load Sharing (DLS), which enables multiple converters to be combined together to deliver higher power if required.<\/p>\n\n\n\n<p>The BMR310 also includes over-voltage, under-voltage, over-current and over-temperature protection functions. As with all Flex Power Modules\u2019 DC\/DC converters, it complies with IEC\/EN\/UL 62368-1 safety standards.<\/p>\n\n\n\n<p>The BMR310 includes a PMBus<sup>\u00ae <\/sup>interface for digital Configuration, Monitoring and Control, and is supported by our own <a href=\"\/flex-power-designer\">Flex Power Designer tool<\/a>.<\/p>\n\n\n\n<p>The BMR310 will be available in Q4 2021, and samples are available now.
