Figure 1. Simplified Schematic
DIP-Packaged, Standard-Pinout
3 Watt, DC/DC Converters
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
trimpots, "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 designers
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 +75C 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 200sec, 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
design-ins in systems demanding small size, low cost and high reliability.

Floating Outputs
Since these are isolated DC/DC converters, their outputs are "floating."
Users 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
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.
To Reduce Input Ripple
"D5" Models
47F, 15V
"D12" Models
10F, 35V
"D48" Models
4.7F, 100V
To Reduce Output Ripple
5V Outputs
47F, 10V, Low ESR
12/15V Outputs
22F, 20V, Low ESR
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.
These are stress ratings. Exposure of devices to any of these conditions may adversely

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.
Application-specific internal input/output filtering can be recommended and perhaps added
internally upon request. Contact DATEL Applications Engineering for details.
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

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.
