DRQ-12/50-L48 Series

www.murata-ps.com

600W Digital Fully Regulated

Intermediate DC-DC Bus Converter

PRODUCT OVERVIEW

Typical unit

The DRQ 600W series provides a fully regulated, and planar magnetics deliver galvanic isolation

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

rated at 2250 Vdc for functional insulation. Target

markets include Networking Equipment, Power

over Ethernet applications, Wireless Network-

ing Equipment, Telecommunications Equipment,

supports advances in power conversion technology Wireless pre-ampliﬁers, Industrial and test equip-

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”

ackage. The DRQ series is an isolated, regulated,

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

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

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

plications.

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 indeﬁnite short-

circuit protection, along with output OVP. The DRQ

series is certiﬁed to safety standards UL/IEC/CSA

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

emission compliance to EN55022, CISPR22 with an

external ﬁlter.
