The DRQ 600W series provides a fully regulated,

digitally controlled DC output in a ¼-brick format

that will support the evolving Advanced Bus Con-

verter (ABC) industry standard footprint for isolated

board mounted power modules. The DRQ series

supports advances in power conversion technology

including a digital interface supporting the PMBus

protocol for communications to power modules.

The DRQ series offers high output current (up to

50 Amps) in an industry standard “quarter brick”

package. The DRQ series is an isolated, regulated,

600W-12Vout quarter brick that has an input range

of 44-60Vdc with a typical efﬁ ciency of 96%. The

DRQ-12/50-L48 is ideal for intermediate bus ap-

plications.

A digitally controlled version is also available

with the Advanced Bus Converter (ABC) pinout.

Advanced automated surface mount assembly

and planar magnetics deliver galvanic isolation

rated at 2250 Vdc for functional insulation. Target

markets include Networking Equipment, Power

over Ethernet applications, Wireless Network-

ing Equipment, Telecommunications Equipment,

Wireless pre-ampliﬁ ers, Industrial and test equip-

ment, 12V Fan trays and applications requiring a

regulated 12V output.

A wealth of self-protection features include input

undervoltage lockout and overtemperature shut-

down; over current protection using the “hiccup”

autorestart technique, provides indeﬁ nite short-

circuit protection, along with output OVP. The DRQ

series is certiﬁ ed to safety standards UL/IEC/CSA

60950-1, 2nd edition. It meets RFI/EMI conducted

emission compliance to EN55022, CISPR22 with an

external ﬁ lter.

DRQ-12/50-L48 Series 600W Digital Fully Regulated Intermediate DC-DC Bus Converter TECHNICAL NOTES (CONT.) Parallel Load Sharing (S Option, 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 3) 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.

DRQ-12/50-L48 Series 600W Digital Fully Regulated Intermediate DC-DC Bus Converter Emissions Performance Murata Power Solutions measures its products for conducted emissions against the EN 55022 and CISPR 22 standards. Passive resistance loads are employed and the output is set to the maximum voltage. If you set up your own emissions testing, make sure the output load is rated at continuous power while doing the tests. The recommended external input and output capacitors (if required) are included.
