Flex Power Modules increase the DC/DC rated power of a quarter brick to 1600 watts continuously, with a peak of 2320 watts
2023-05-29
Flex Power Modules has launched a new device for its quarter brick non isolated DC/DC converter series, bringing power density to new levels. The input range of BMR351 is 40-60V, providing a non isolated but fully adjustable 12.2V rated output. The rated output current is 136 A continuous current (maximum 1600 W) and 200 A peak, with a maximum length of 500 ms (maximum 2320 W). The converter has a very high efficiency level, with a peak value of over 98%, and a typical value of 97.8% at 54Vin and half load.
The BMR351 converter can be paralleled using droop load sharing technology to achieve higher power, and includes a PMBus interface for configuration, monitoring, and control. The output can be adjusted in the range of 8V to 13.2V, providing hardware pins for remote sensing, good power supply, and remote control. The innovative "black box" event data recorder for flexible power modules has also been implemented for diagnosis after faults occur.
BMR351 is used for bottom plate cooling, characterized by a component hot spot temperature of 125 ℃. Comprehensive thermal management allows for safe peak power operation, with fast and timed over temperature protection, and an ALERT signal to indicate impending thermal shutdown. Like other Flex Power Modules DC/DC products, the data is represented by using a "3D" derating diagram to describe the power output of the component, defining the allowable output power at the specified maximum base and pin temperatures. The converter also includes input undervoltage locking and output short-circuit, overvoltage, and overcurrent protection.
BMR351 is supported by the Flex Power Designer tool for electrical and thermal simulation of terminal applications.
Ole Hellgren, Director of Product Management and Marketing at Flex Power Modules, commented, "Our BMR351 is an ideal choice for applications that require maximum power density and high rated peak power, such as in servers and cloud applications.
