UWQ-12/17-Q48 Series

Wide Input, Isolated DOSA Quarter Brick DC/DC Converters

www.murata-ps.com

PRODUCT OVERVIEW

The UWQ series offers high output current (up to

17 Amps) in an industry standard “quarter brick”

package requiring no heat sink for most applica-

tions. The UWQ series delivers ﬁxed DC output

voltages up to 204 Watts (12V @17A) for printed

circuit board mounting. Wide range inputs of 18

to 75 Volts DC (48 Volts nominal) are ideal for

datacom and telecom systems.

Advanced automated surface mount assembly

and planar magnetics deliver galvanic isolation

rated at 2250 Vdc for basic insulation. To power

digital systems, the outputs offer fast settling to

current steps and tolerance of higher capacitive

loads. Excellent ripple and noise speciﬁcations as-

sure compatibility to CPU’s, ASIC’s, programmable

logic and FPGA’s. No minimum load is required.

For systems needing controlled startup/shutdown,

an external remote On/Off control may use either

positive or negative polarity.

A wealth of self-protection features include

input undervoltage lockout and overtemperature

shutdown using an on-board temperature sensor;

overcurrent protection using the “hiccup” auto-

restart technique, provides indeﬁnite short-circuit

protection, along with output OVP. The synchronous

rectiﬁer topology offers high efﬁciency for minimal

heat generation and “no heat sink” operation. The

UWQ series is certiﬁed to safety standards UL/

EN/IEC/CSA 60950-1, 2nd edition. It meets RFI/

EMI conducted/radiated emission compliance to

EN55022, CISPR22 with an external ﬁlter.
