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 com-

munications to power modules.

The DBQ series also incorporates a “droop” load

sharing option that allows connecting two or more

units 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 cov-

ering MicroTCA, servers and storage applications,

networking equipment, telecommunications equip-

ment, Power over Ethernet (PoE), fan trays, wireless

networks, wireless pre-ampliﬁ ers, and industrial

and test equipment, along with other applications

requiring a regulated 12V.

DBQ/DVQ Series 420W Digital Fully Regulated Intermediate DC-DC Bus Converter TECHNICAL NOTES (CONT.) Parallel Load Sharing (S Option, Droop Load Sharing) Two or more converters may be connected in parallel at both the input and output terminals to support higher output current (total power, see ﬁgure 2) or to improve reliability due to the reduced stress that results when the modules are operating below their rated limits. For applications requiring current share, followed the guidelines below.

Load Sharing Block Diagram Input Under-Voltage Shutdown and Start-Up Threshold Converters will not begin to regulate properly until the rising input voltage exceeds and remains at the Start-Up Threshold Voltage (see Speciﬁcations). Once operating, converters will not turn off until the input voltage drops below the Under-Voltage Shutdown Limit.
