BMR350 2100/031H

he BMR350 is a non-isolated digital Intermediate Bus Converter (IBC) with PMBus® interface. The device delivers up to 1300 W of continuous power at efficiency levels of >97.8% (measured at half load) in an industry standard quarter brick measuring 58.4 x 36.8 x 12 mm, which includes an integrated “open deck” baseplate enabling simplified conduction cooling to the customers’ heatsink or cold plate. Peak power delivery of up to 1700 W (140 A) is also possible for short durations (<1s). The input voltage range is 40-60 V which is suitable for 48/54 V applications such as those found in Data Centers, High Performance Computing and Cloud Computing applications for example, and the fully regulated output voltage of 12 V nominal (adjustable from 8-13.2 V) makes it suitable to be used to power downstream Point of Load (PoL) converters and integrated power stages such as the BMR510, as well as powering circuitry that needs a tightly regulated output. Key Benefits The BMR350 offers another alternative solution to Flex Power Modules' customers when choosing an IBC for systems transitioning from legacy 12V feeds to a 48V feed. The fully regulated output and industry standard design makes it suitable for a wide variety of applications. The BMR350 includes an Event Data Recorder feature (also known as a "Black Box"), which automatically stores essential operational condition information to a non-volatile memory in case of a fault/shutdown or catastrophic failure, which is hugely beneficial with fault diagnosis and failure analysis since it can be interrogated via the PMBus® interface. An innovative transformer-coupled non-isolated topology reduces component count and current stresses, and delivers efficiency levels of up to 97.8%. Paralleling of the converters is supported using passive Active Current Sharing (ACS), which enables multiple converters to be combined together to deliver higher power if required. The BMR350 also includes over-voltage, under-voltage, over-current and over-temperature protection functions. As with all Flex Power Modules’ DC/DC converters, it complies with IEC/EN/UL 62368-1 safety standards.
