Murata Power Solutions is introducing the first in a series of digitally controlled DC-DC converters that are based on a 32-bit ARM processor. The DBE series provides a fully regulated, digitally controlled DC output in an eighth-brick format that will support the evolving, Advanced Bus Converter (ABC) industry standard footprint for isolated board mounted power modules. The DBE series supports advances in power conversion technology including a digital interface supporting the PMBus protocol for communications to power modules.  

The DBE series products are eighth-brick DC-DC converter with a digital interface supporting the PMBus standard for communicating with power devices. The DBE series also supports the TNV standard for input Voltage with a 36–75Vin specified Vin range and was designed to provide payload power in distributed power architectures. The DBE offers a “droop” load sharing option for paralleling modules in the most demanding, power hungry applications or to provide redundancy in high reliability applications. The converter also offers high input to output isolation of 2250 VDC as required for Power over Ethernet (PoE) applications. The DBE series is suitable for applications covering MicroTCA, servers and storage applications, networking equipment, Power over Ethernet (PoE), fan trays, wireless networks, wireless pre-amplifiers, industrial and test equipment along with other applications requiring a regulated 12V and 5V.
