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.
