PRODUCT OVERVIEW
Rarely has a Series of low-power DC/DC con-
verters been defined by both low ost and DATEL's
response is a quick 200µsec, while output ripple
and noise are typically 75mVp-p.

UST Series of single-output DC/D’s achieves this
best-of-both-worlds status by implementing a
These rugged modules are fully encapsulated
with a thermally conductive potting compound that
contributes to their outstanding moisture/vibration
resistance and impressive MTBF. They operate over
the full –40 to +75°C temperature range without
derating. All models have been thoroughly charac-
terized (electrically, mechanically and thermally),
qualified (including HALT), and EMI/EMC tested.
Additionally, they are certified to UL1950, CSA 22.2
No. 950 and IEC950.
DATEL’s UST Model 3W DC/DC’s are excellent
selections for telecom/datacom, computer and
process-control applications demanding small size,
low cost and high reliability. If required, their design
"flexibility" allows for easy modification to your
application-specific requirements.

surace-mounmagnecsat is truly 100% auto-
matically assembled. Packaged in miniature 1.25"
x 0.8", DIP-like plastic packages (UL94V-0 rated)
and requiring no external components, UST Series
DC/DC’s bring true component-like convenience to
designers of today’s distributed power systems.
Output voltages are 5, 12 or 15 Volts. Input

All UST 3 Watt DC/DC Converters achieve their rated ripple and noise
specifications without the use of external input/output capacitors. In criti-
cal 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.

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 for quantity orders
and perhaps added internally upon request. Contact DATEL Applications Engineering for
details.
To Reduce Input Ripple
➂ Devices can be screened for quantity orders or modified for higher guaranteed isolation
voltages. Contact DATEL Applications Engineering for details.
➃ The current limit inception point is dependent on the input voltage. Therefore, it is possible
to draw current beyond the rated capacity. Users should fully characterize their load condi-
tions.

If you’re designing with EMC in mind, please note that all of DATEL’s
UST 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 UST-5/500-D48 appear below.
