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-efficient (as high as 76% guaranteed), fully isolated (1000Vdc

minimum), DIP-packaged power converters provide true component-like convenience

and flexibility to designers of modern distributed power systems.

Exploiting high-frequency (170-200kHz), flyback topologies and contemporary,

highly automated, SMT assembly techniques, UWR Model DC/DC’s have enough space

to include input (pi type) and output filters 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 encapsulated with a thermally conductive

potting compound. They are moisture and vibration resistant and have established a

reputation for outstanding MTBF. For telecommunication, computer and other EMI-

sensitive applications, these DIP-packaged DC/DC converters offer full EMI/EMC

characterization data.

DATEL’s UWR Model 3W DC/DC’s are ideal replacements 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.
