Single Output  
A-Series, UWR Models  
High-Density, 1" x 2"  
6 Amp/15 Watt, 1.2-15VOUT DC/DC's  
A - S E R I E S  
The new 1.2, 1.5V, 1.8V and 2.5V models in DATELs flagship 7-15 Watt A-Series  
can source a continuous 6 Amps. This is the most "low-voltage" current available  
from a standard 1" x 2" package, and these power converters exemplify DATELs  
relentless drive to bring you more power/current, from standard packages, without  
compromising reliability or resorting to thermal specmanship.  
By combining a high-frequency, high-efficiency (to 88%), synchronous-rectifier  
topology with the newest components and time-tested, fully automated, SMT-on-pcb  
construction, these UWR Models are able to bring you 7-15W (@ up to 6A) in the  
standard 1" x 2" package from which most competitors can only get 5-10W (@  
3-4A). All UWR’s deliver their full output power over ambient temperature ranges  
from –40°C to as high as +70°C (model and input voltage dependent) without heat  
sinks or supplemental forced-air cooling. Devices derate to +100°C.  
Output voltages are 1,2, 1.5, 1.8, 2, 2.5, 3.3, 5, 12 or 15 Volts. Input voltage  
ranges are 10-18V (D12 models), 18-36V (D24 models) or 36-75V (D48 models).  
All models feature input pi filters, input undervoltage and overvoltage lockout, input  
reverse-polarity protection, output overvoltage protection, output current limiting,  
and continuous short-circuit protection. On/off control and output-trim functions are  
optional (see Optional Functions). All models are certified to IEC950, UL1950 and  
EN60950 safety requirements. D48 models (36-75V inputs) are CE marked.  
UWR 7-15W DC/DC’s are packaged in low-cost, light-weight, diallyl phthalate  
(UL94V-0 rated) plastic packages with standoffs. EMC compliance is achieved via a  
low-noise design rather than through expensive metal shielding.  
Features  
1.2-2.5VOUT models source 6 Amps  
3.3VOUT models source 4.25 Amps  
5/12/15VOUT models deliver full 15Watts  
Synchronous-rectifier topologies  
Guaranteed efficiencies to 88%
