FEATURES
PRODUCT OVERVIEW
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
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
