Second generation 48V-to-load Direct Conversion technology
Up to 91.3% efficiency from the cost-effective DC/DC converter
Board space requirements up to 50% lower than two-stage architecture
Scalable multi-phase design can deliver up to 660 A from six modules in parallel
Flex Power Modules introduces the BMR482, its second generation of direct conversion isolated DC/DC converter. By converting directly from a 48 V supply to the load voltage without an intermediate stage, the BMR482 delivers increased efficiency in a compact package, enabling it to meet the higher power needs of today’s data centers and cloud computing.
The BMR482 can achieve up to 91.3% efficiency with a 0.8 V output at 53 Vin, which is 2 to 3% better than an equivalent solution based on an intermediate bus converter (IBC) and point of load (PoL). The single-stage BMR482 also requires up to 50% less board space than a conventional two-stage solution, helping reduce overall costs.
