DBQ Series DC-DC Converters

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 DBQ series provides a fully regulated, digitally controlled DC output in a quarter-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.

The DBQ0135V2 is an isolated, regulated, 420 W-12 VOUT quarter-brick that supports the TNV input voltage range of 36 V - 75 V with a typical efficiency of 95.2%. The DBQ series also incorporates a “droop” load-sharing option that allows connecting three modules together in parallel for 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 DBQ series is suitable for applications covering MicroTCA, servers and storage applications, networking equipment, telecommunications equipment, Power over Ethernet (PoE), fan trays, wireless networks, wireless pre-amplifiers, and industrial and test equipment, along with other applications requiring a regulated 12 V.
