Performance/Functional Specifications
Typical @ T
➀ These converters require a minimum 10% loading to maintain specified regulation. Operation
➁ Application-specific internal input/output filtering can be recommended and perhaps added
➂ Applying a voltage to the Control pin when no input power is applied to the converter
➃ "D48A" models have BASIC, all other models have Functional insulation.
➄ Except for 3.3V outputs which have no protection.

Single Output, High Reliability, 2" x 2", 14-20 Watt, DC/DC Converters
➀
Floating Outputs
Since these are isolated DC/DC converters, their outputs are "floating."
Users may ground either the Common (pin 7) for normal usage or the
positive side (+Output, pin 6) to effectively reverse the output polarity.
Filtering and Noise Reduction
All A-Series UWR 14-20 Watt DC/DC Converters achieve their rated ripple
and noise specifications without the use of external input/output capacitors.
In critical applications, input/output noise may be further reduced by installing
electrolytic capacitors across the input terminals and/or low-ESR tantalum
or electrolytic capacitors across the output terminals. The caps should be
located as close to the power converters as possible. Typical values are
listed below. In many applications, using values greater than those listed
will yield better results.
In critical, space-sensitive applications, DATEL may be able to tailor the
internal input/output filtering of these units to meet your specific require-
ments. Contact our Applications Engineering Group for additional details.
