[Murata-Ps]

PRODUCT OVERVIEW
Murata Power Solutions is introducing the fi rst in a series of digitally controlled DC-DC converters that are based on a 32-bit ARM processor. The DBQ series provides a fully regulated, digitally controlled DC output in a ¼-brick format that will support the evolving Advanced Bus Converter (ABC) industry standard footprint for isolated board mounted power modules. The DBQ series supports advances in power conversion technology including a digital interface supporting the PMBus protocol for communications to power modules.
