The BMR351 has a 40-60 V input range and a delivers a non-isolated but fully regulated output of 12.2 V nominal. Rated output current is 136 A continuous (1600 W max) and 200 A peak for up to 500 ms (2320 W max). The efficiency levels peaks at over 98%, and with a typical value of 97.8% at 54 Vin and half load.
The BMR351 DC-DC converter range can be paralleled using the droop load sharing technique for higher power, and include a PMBus interface for configuration, monitoring and control, with the output adjustable over the range of 8 V to 13.2 V. Hardware pins are provided for remote sense, power good and remote control. The Flex Power Modules innovative ‘black box’ event data recorder is also implemented for diagnostics after fault occurrences. Lcd Module Tft
The BMR351 is intended for baseplate cooling and is characterized for a component hotspot temperature of 125 °C. Comprehensive thermal management allows safe peak power operation with fast and timed over-temperature protection, with an ALERT signal to indicate impending thermal shutdown.
The data sheet now characterizes the parts power delivery with ‘3D’ derating graphs defining allowable output powers at specified maximum baseplate and pin temperatures. The converter also includes input under-voltage lockout and output short-circuit, over-voltage, and over-current protection.
“Our BMR351 is ideal when maximum power density is needed along with high peak power rating, such as in server and cloud applications,” said Olle Hellgren, Director Product Management and Marketing of Flex Power Modules.
The BMR351 is supported by the Flex Power Designer Tool for electrical and thermal simulation in the end-application.
