These converters require a minimum 10% output loading to maintain specified regulation.
Operation under no-load conditions will not damage these devices; however they may not
meet all listed specifications.
Application-specific input/output filtering can recommended or perhaps added
internally upon request. Contact DATEL Applications Engineering for details.
Applying voltage to the Control pin with no input power applied can damage the converter.
The On/Off function can be replaced with a Sync function. See page 3-48 for more details.
Listed spec is for input-to-output. Input-to-case and output-to-case isolation is 1000Vdc min.

These are stress ratings. Exposure of devices to any of these conditions may adversely
affect long-term reliability. Proper operation under conditions other than those listed in the
Performance/Functional Specifications Table is not implied.
TECHNICAL NOTES
Floating Outputs
Since these are isolated DC/DC converters, their outputs are "floating."
Users may ground either the Common (pin 8) for normal usage or the
positive side (+Output, pin 9) to effectively reverse the output polarity.
Filtering and Noise Reduction
All UMP 25-40 Watt DC/DC Converters achieve their rated ripple and noise
specifications without the use of external input/output capacitors. In critical
applications, input/output ripple and 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 in the tables 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 devices to meet your specific require-
ments. Contact our Applications Engineering Group for additional details.
Input Fusing
Certain applications and/or safety agencies may require the installation of
fuses at the inputs of power conversion components. For DATEL UMP
DC/DC Converters, you should use slow-blow type fuses with values no
greater than the following:
