PRODUCT OVERVIEW
UST Models
3W, Single Output DC/DC Converters
NOT RECOMMENDED
FOR NEW DESIGNS
Rarely has a Series of low-power DC/DC con-
verters been de ? ned 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 ?yback
design) as a full, SMT-on-pcb assembly (including
surface-mount magnetics) that is truly 100% auto-
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 charac-

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
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
?lters within their package. Output transient
terized (electrically, mechanically and thermally),
quali?ed (including HALT), and EMI/EMC tested.
Additionally, they are certi?ed 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
"?exibility" allows for easy modi?cation to your
application-speci?c requirements.
