UWQ-12/17-Q48 Series  
Wide Input, Isolated DOSA Quarter Brick DC/DC Converters  
s
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.
