Performance/Functional Specications
Floating Outputs
Since these are isolated DC/DC converters, their outputs are "oating." Us-
ers may ground either the Common (pins 5 and 7) for normal usage or the
positive side (+Output, pins 6 and 8) to effectively reverse the output polarity.
Filtering and Noise Reduction
All UWR 3 Watt DC/DC Converters achieve their rated ripple and noise
specications without the use of external input/output capacitors. In critical
applications, input/output ripple and noise may be further reduced by install-
ing electrolytic capacitors across the input terminals and/or low-ESR tanta-
lum 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.
To Reduce Input Ripple
"D5" Models
47μF, 15V
"D12" Models
10μF, 35V
"D48" Models
4.7μF, 100V
To Reduce Output Ripple
5V OutputS
47μF, 10V, Low ESR
12/15V Outputs
22μF, 20V, Low ESR
In critical, space-sensitive applications, DATEL may be able to tailor the inter-
nal input/output ltering of these units to meet your specic requirements.

These power converters require a minimum 10% loading to maintain specied regulation.
Operation under no-load conditions will not damage these devices; however they may not
meet all listed specications.
Application-specic internal input/output ltering can be recommended and perhaps
added internally upon request. Contact DATEL Applications Engineering for details.
Devices can be screened or modied for higher guaranteed isolation voltages.
Contact DATEL Applications Engineering for details.
Devices can be warranted or screened for lower-temperature operation.
Contact DATEL Applications Engineering for details.
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 Specications Table is not implied.
