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 EMIsensitive 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.

Since these are isolated DC/DC converters, their outputs are "floating." Users may ground either the Common (pins 5 and 7) for normal usage or the positive side (+Output, pins 6 and 8) to effectively reverse the output polarity. Filtering and Noise Reduction All UWR 3 Watt DC/DC Converters achieve their rated ripple and noise specifications without the use of external input/output capacitors. In critical 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. The caps should be located as close to the power converters as possible. Typical values are listed in the tables below. In many applications, using values greater than those listed will yield better results.

These power converters require a minimum 10% loading to maintain specified regulation. Operation under no-load conditions will not damage these devices; however they may not meet all listed specifications. Application-specific internal input/output filtering can be recommended and perhaps added internally upon request. Contact DATEL Applications Engineering for details. Devices can be screened or modified for higher guaranteed isolation voltages. Contact DATEL Applications Engineering for details. Devices can be warranted or screened for lower-temperature operation. Contact DATEL Applications Engineering for details. See DATEL's new UST 3W Models for guaranteed operation to 40°C.
In critical, space-sensitive applications, DATEL may be able to tailor the internal input/output filtering of these units to meet your specific requirements. Contact our Applications Engineering Group for additional details.
