Flex Power Modules has introduced a new device for its line of quarter-brick non-isolated DC/DC converters

     Flex Power Modules has introduced a new device for its line of quarter-brick non-isolated DC/DC converters that takes power density to a new level. The BMR351 has an input range of 40-60V and offers a non-isolated but fully regulated 12.2V rated output. The rated output current is 136 A continuous current (Max 1600 W) and 200 A peak, up to 500 ms (Max 2320 W).

     Olle Hellgren, Director of Product Management and Marketing at Flex Power Modules, commented: "Our BMR351 is ideal for applications that require maximum power density and high peak power ratings, such as in server and cloud applications. The converter has an extremely high efficiency level with a peak of over 98% and a typical value of 97.8% at 54Vin and half load.

     The BMR351 converter can be connected in parallel using vertical load sharing technology for higher power, and includes a PMBus interface for configuration, monitoring and control, with output adjustable in the range of 8V to 13.2V, providing hardware pins for remote sensing, good power supply and remote control. The flexible power module's innovative "black box" event data logger is also implemented for diagnosis after a fault has occurred.

     The BMR351 is used for base plate cooling and is characterized by a hot spot temperature of 125 ° C. Comprehensive thermal management allows safe peak-power operation, with fast and timed overtemperature protection and an ALERT signal to indicate impending thermal shutdowns. As with other Flex Power Modules DC/DC products, the data is represented in a "3D "derated plot that describes the power output of the part, defining the allowable power output at a specified maximum base and pin temperature. The converter also includes input undervoltage lock and output short-circuit, overvoltage and overcurrent protection.
