UWQ-12/20-T48 Series

Wide Input, Isolated DOSA Quarter Brick DC/DC Converters

PRODUCT OVERVIEW

The UWQ series offers high output current (up to

20 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 240 Watts (12V @20A) for printed

circuit board mounting. Wide range inputs of 18

to 60 Volts DC (48 Volts nominal) are ideal for

datacom and telecom systems.

The UWQ-12/20-T48NS/PS offers a load shar-

ing option for paralleling up to three modules in

the most demanding, power hungry applications.

Advanced automated surface mount assembly and

planar magnetics deliver galvanic isolation rated at

2250 Vdc for basic insulation. To power digital sys-

tems, the outputs offer fast settling to current steps

and tolerance of higher capacitive loads. Excellent

ripple and noise speciﬁcations assure compatibility

to CPUs, ASICs, programmable logic and FPGAs.

No minimum load is required. For systems needing

controlled startup/shutdown, an external remote

On/Off control may use either positive or negative

logic.

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/

IEC/CSA 60950-1, 2nd edition. It meets class B

EMI conducted emission compliance to EN55022,

CISPR22 with an external ﬁlter.
