The proven cost-effectiveness, quality and long-term reliability that has come
to define DATEL’s standard, 3W, single-output, DIP-packaged DC/DC converters
(see UST 3W Models) is now available in the "other standard pinout" (see next
page) made popular by off-shore suppliers. These newly designed UWP Models
exploit totally automated SMT assembly techniques and do not contain any trim-
pots, "wet" aluminum electrolytic capacitors, or manually soldered "flying" leads.
Their made-in-the-USA quality and affordable pricing are rapidly making them
the converters of choice in many existing applications.
UWP DC/DC converters bring true component-like convenience to design-
ers of modern distributed power systems. Exploiting an efficient, high-frequency
(170-200kHz), flyback topology and high-density SMT assembly techniques,
UWP DC/DC’s have enough space to include input (pi type) and output filters
within their package. They are fully isolated (500Vdc guaranteed) and do not
require any external components to meet published specifications. They operate,
without derating, over the full –40 to +75°C temperature range.
Output voltages are either 5, 12 or 15 Volts. Input voltage ranges are either
4.5-9V ("D5" models), 9-18V ("D12" models) or an ultra-wide 18-72V ("D48"
models). Output transient response time is a quick 200µsec, and output ripple
and noise are typically 75mVp-p. All models are certified to UL1950, CSA 22.2
No. 950 and IEC950. Full EMI/EMC characterizations are currently in progress.
DATEL’s UWP Model 3W DC/DC’s are ideal replacements for other more
costly, less reliable power converters as well as excellent choices for new de-
sign-ins in systems demanding small size, low cost and high reliability.

Floating Outputs
Since these are isolated DC/DC converters, their outputs are "floating." Us-
ers may ground either the negative side (–Output, pins 10 and 15) for normal
usage or the positive side (+Output, pins 11 and 14) to effectively reverse the
output polarity.
Filtering and Noise Reduction
All UWP 3 Watt DC/DC Converters achieve their rated ripple and noise speci-
fications without the use of external input/output capacitors. In critical ap-
plications, 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.

➀
These power converters require a minimum 10% loading to maintain specified regulation.
Operation under no-load conditions will not damage these devices; however
they may not meet all listed specifications.
➁
Application-specific internal input/output filtering can be recommended and perhaps
added internally upon request. Contact DATEL Applications Engineering for details.
➂
Devices can be screened or modified for higher guaranteed isolation voltages.
Contact DATEL Applications Engineering for details or see DATEL's UST 3W DC/DC's
for guaranteed 1000Vdc isolation.
In critical, space-sensitive applications, DATEL may be able to tailor the in-
ternal input/output filtering of these units to meet your specific requirements.
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 UWP 3

EMI RADIATED EMISSIONS
If you’re designing with EMC in mind, please note that all of DATEL’s
UWP 3 Watt DC/DC Converters have been characterized for radiated and
conducted emissions in our new EMI/EMC laboratory. Testing is conducted
in an EMCO 5305 GTEM test cell utilizing EMCO automated EMC test
software. Radiated emissions are tested to the limits of FCC Part 15, Class
B and CISPR 22 (EN 55022), Class B. Correlation to other specifications
can be supplied upon request. Radiated emissions plots to FCC and CISPR
22 for model UWP-15/200-D5 appear below. Published EMC test reports are
available for each model number. Contact DATEL’s Applications Engineering
Department for more details.
