PRODUCT OVERVIEW

verters been deﬁ 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 ﬂ yback

design) as a full, SMT-on-pcb assembly (including

surface-mount magnetics) that 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.

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

ﬁ lters within their package. Output transient

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),

qualiﬁ ed (including HALT), and EMI/EMC tested.

Additionally, they are certiﬁ ed to UL1950, CSA 22.2

No. 950 and IEC950.

... Filtering and Noise Reduction All UST 3 Watt DC/DC Converters achieve their rated ripple and noise speciﬁ cations 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 ...
