Flex Power Modules announces the launch of the BMR490, a non-isolated digital IBC (Intermediate Bus Converter) DC-DC converter with an output power of 1300W in the quarter-brick form factor. The new converter combines very high power density with excellent thermal performance in a price-sensitive design, making it ideal for demanding applications such as data centres.
- High efficiency of 97.3% (typical)
- Digital interface with PMBus makes it simpler to fine-tune functionality
- Excellent thermal performance reduces system costs, and makes thermal design
easier for electronics engineers
In developing the converter, Flex Power Modules has registered more than 10 patents, which in part have led to significant improvements in the area of thermal management within the converter. To help with the thermal performance, manufacturing has also been improved, with the baseplate screwed directly to the converter’s PCB. Together, these measures lead to an increase of usable power from the BMR490 of over 20% when compared to similarly rated modules in extended temperatures.
The BMR490 provides a digital interface fully compliant to PMBus 1.3, which makes it simple to reconfigure, and therefore to fine-tune the functionality to respond to the requirements of a particular application. The converter can be configured using the Flex Power Designer software, which provides detailed simulations including thermal modelling, and therefore helps reduce development time and minimise the risk of weaknesses in a power system design.
