DRQ-12/50-L48 Series
600W Digital Fully Regulated
Intermediate DC-DC Bus Converter
PRODUCT OVERVIEW
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 efficiency 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-amplifiers, 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 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.
APPLICATIONS
Embedded systems, datacom and telecom
installations, wireless base stations
Disk farms, data centers and cellular repeater sites
Remote sensor systems, dedicated controllers
Instrumentation systems, R&D platforms, auto-
mated test fixtures
Data concentrators, voice forwarding and
speech processing systems
