UST Models
3W, Single Output DC/DC Converters
Features
Rarely, has a Series of low-power DC/DC converters been defined by both low
cost and DATEL's made-in-the-USA quality and reliability. Our new UST Series of
single-output DC/DC’s achieves this best-of-both-worlds status by implementing
a proven circuit architecture (170-200kHz flyback design) as a full, SMT-on-pcb
assembly (including surface-mount magnetics) that is truly 100% automatically
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 voltage ranges are 4.5-9V ("D5"
models), 9-18V ("D12" models) or an ultra-wide 18-72V ("D48" models). UST
DC/DC’s are fully isolated (1000Vdc guaranteed) and include input (pi type) and
output filters within their package. Output transient response is a quick 200µsec,
while output ripple and noise are typically 75mVp-p.
These rugged modules are fully encapsulated with a thermally conductive pot-
ting 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 characterized (electrically, me-
chanically and thermally), qualified (including HALT), and EMI/EMC tested. Addition-
ally, 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.

Physical
Filtering and Noise reduction
All UST 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.
Dimensions
1.25" x 0.8" x 0.45" (31.8 x 20.3 x 11.4mm)
Case Material
Diallyl phthalate, UL94V-0-rated
Pin Material
Gold-plated copper alloy w/nickel underplate
Weight
0.5 ounces (14.2 grams)
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.
➃ The current limit inception point is dependent on the input voltage. Therefore, it is possible

Input Fusing
Certain applications and/or safety agencies may require the installation of
fuses at the inputs of power conversion components. For DATEL UST 3

EMI raDIaTED EMISSIONS
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. Published EMC test reports are
available for each model number. Contact DATEL’s Applications Engineering
Department for more details.
