ULQ Models  
Single Output, Low-Profile, Quarter-Brick  
8-25 Amp Isolated DC/DC Converters  
Typical units  
Features  
For applications requiring improved electrical and thermal perfomance at  
reduced cost DATEL's new ULQ Series "Quarter-Brick" DC/DC Converters suit  
perfectly. They measure just 1.45 x 2.30 x 0.35 inches (36.8 x 58.4 x 8.9mm) and fit  
the industry-standard footprint.You can also "pick-and-place" the ULQ-SMT version  
optimizing your automated SMT process.  
From an 18-36V or 36-75V input, ULQ's deliver outputs of 1.2, 1.5, 1.8, or 2V  
fully rated at 15 or 25A, 2.5 or 3.3V at 15 or 20A, 5V at 15A and 12V at 8-10A. They  
employ an interleaved, synchronous-rectifier topology that exploits 100% of their duty  
cycle. They simultaneously achieve ultra-high efficiency (to 91%), tight line/load regu-  
lation ( 0.125/0.25%), low noise (25-70mVp-p), and quick step response (200μsec).  
A state of the art, single-board, open-frame design with reduced component  
count, high efficiency, low-on-resistance FET's, and planar magnetics embedded in  
heavy-copper pc boards all contribute to impressive thermal derating.  
The ULQ's feature set includes high isolation (2250Vdc), input pi filters, input  
undervoltage shutdown, output overvoltage protection, current limiting, short-circuit  
protection and thermal shutdown. The standard footprint carries on/off control (posi-  
tive or negative polarity), output trim (+10/–20%) and output sense functions.  
All ULQ quarter-bricks are designed to meet the BASIC-insulation requirements  
of UL/EN/IEC60950 and they will carry the CE mark. Safety certifications, EMC  
compliance testing and qualification testing (including HALT) are currently in prog-  
ress. Contact DATEL for latest updates.
