The 3 Watt, single-output, UWR Models of DATEL's
XWR Series DC/DC converters deliver impressive
levels of cost-effectiveness in an industry-standard
package and pinout. These highly-ef?cient (as
high as 76% guaranteed), fully isolated (1000Vdc
minimum), DIP-packaged power converters provide
true component-like convenience and ?exibility to
designers of modern distributed power systems.
Exploiting high-frequency (170-200kHz), ?yback
topologies and contemporary, fully automated, SMT
assembly techniques, UWR Model DC/DC’s have
enough space to include input (pi type) and output
?lters within their package. Requiring no external
components, these converters offer true "plug-and-
play" convenience. They operate over the full –25
to +75°C temperature range with no output power
derating.
Output voltages are either 5, 12 or 15 Volts. Input
voltage ranges are either 4.5-9V ("D5" models),
9-18V ("D12" models) or an ultra-wide 18-72V
("D48" models). Transient response time is a quick
200μsec.
These extremely rugged modules are fully encap-
sulated with a thermally conductive potting com-
pound. They are moisture and vibration resistant
and have established a reputation for outstanding
MTBF. For telecommunication, computer and other
EMI-sensitive applications, these are the only DIP
packaged DC/DC’s offering full EMI/EMC character-
ization data.
DATEL’s UWR Model 3W DC/DC’s are ideal replace-
ments for other more costly, less reliable power
converters as well as excellent choices for new
design-ins in systems demanding small size, low
cost and high reliability.
