Low-Cost, High-Reliability

3 Watt, DC/DC Converters

Rarely, has a Series of low-power DC/DC converters been defined by both low
cost and DA TEL'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
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 characterized (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.
