The DRQ 500W 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

43.5 Amps) in an industry standard “quarter brick”

package. The DRQ series is an isolated, regulated,

500W-11.5Vout quarter brick that supports the

TNV input voltage range of 38V-75V with a typical

efﬁ ciency of 95.5%.

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 networking equip-

ment, telecommunications equipment, wireless

pre-ampliﬁ ers, industrial and test equipment, and

applications requiring a regulated 11.5V 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-12/42-D48 Series 500W Digital Fully Regulated Intermediate DC-DC Bus Converter TECHNICAL NOTES (CONT.) Thermal Shutdown Extended operation at excessive temperature will initiate overtemperature shutdown triggered by a temperature sensor outside the PWM controller. This operates similarly to overcurrent and short circuit mode. The inception point of the overtemperature condition depends on the average power delivered, the ambient temperature and the extent of forced cooling airﬂow.

DRQ-12/42-D48 Series 500W Digital Fully Regulated Intermediate DC-DC Bus Converter Minimum Output Loading Requirements All models regulate within speciﬁcation and are stable under no load to full load conditions. Thermal Shutdown (OTP, UTP) To prevent many over temperature problems and damage, these converters include thermal shutdown circuitry.
PAGE 22
DRQ-12/42-D48 Series 500W Digital Fully Regulated Intermediate DC-DC Bus Converter The remote Sense lines carry very little current. They are also capacitively coupled to the output lines and therefore are in the feedback control loop to regulate and stabilize the output. As such, they are not low impedance inputs and must be treated with care in PC board layouts. Sense lines on the PCB should run adjacent to DC signals, preferably Ground.

DRQ-12/42-D48 Series 500W 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.
