PRODUCT OVERVIEW
The UWQ-12/17-Q48T series offers high output
current (up to 17 Amps) in an industry standard
“quarter brick” package requiring no heat sink
for most applications. The UWQ-12/17-Q48T is
trimmable from 10.8Vout to 13.2Vout and includes
output sense pins to compensate for output voltage
inaccuracy delivered at the load. The UWQ-12/17-
Q48T 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 wireless base sta-
tions, datacom, and telecom systems.
Advanced automated surface mount assembly,
thermal management technology, and planar
magnetics deliver high reliability galvanic isolation
rated at 2250 Vdc for basic insulation. To power
digital systems, the output delivers fast settling to
current steps and stable operation where higher
capacitive loads are required. Excellent ripple and
noise specifications deliver stable 12V BUS for
IBC applications. For systems needing controlled
startup/shutdown, an external remote On/Off con-
trol may use either positive or negative logic.
Several self-protection features include input un-
dervoltage lockout, output overvoltage protection,
and overtemperature shutdown (using an on-board
temperature sensor); overcurrent protection us-
ing the “hiccup” autorestart technique provides
indefinite short-circuit protection. The synchronous
rectifier topology along with advanced thermal
management delivers high efficiency for minimal
heat generation and “no heat sink” operation.
The UWQ-12/17-Q48T series is certified to
safety standards UL/EN/IEC/CSA 60950-1, 2nd
edition. It meets Class B EMI conducted emission
compliance to EN55022, CISPR22 with an external
filter.
