The migration to distributed power is accelerating. The critical need for accurate voltages, tight regulation and rapid transient response is propelling the move to power processing at the "point-of-use" with low-power DC/DC converters physically located right at their loads. DATEL's miniature, full featured, 5 Watt UWR Models were specifically designed for today's demanding distributed power architectures in aerospace, marine, telecom and computer applications. The converters' low cost, small size (1" x 1" x 0.45") and full 5 Watt output capability give system architects unprecedented design and layout flexibility. Occupying less than 0.5in3 total volume, these extremely compact, fully regulated and isolated (1000Vdc guaranteed) modules are available with either 5, 12 or 15 Volt outputs. Input voltage ranges are either 18-36 Volts ("D24" models) or 36-72 Volts ("D48" models). Although their overall size is 50-75% smaller than many similarly rated power modules, these 1" x 1" UWR Models are exact, drop-in, pin-for-pin replacements for many standard 2" x 1" and 2" x 2", 5 Watt modules. They achieve their small size and low cost by exploiting a novel feedback approach that does not depend upon traditional optocoupler techniques. All models are 5-side shielded and have a non-conductive baseplate that permits pccard runs to be placed beneath the package. Units are assembled using high-speed automated SMT techniques and are fully encapsulated with thermally conductive potting compound. Every unit is electrically tested before and after encapsulation, 100% burnedin under full load, hi-pot tested, and final-electrical tested prior to shipment. Every unit meets DATEL's traditional high standards for quality and long-term reliability.

Floating Outputs Since these are isolated DC/DC converters, their outputs are "floating." Users may ground either the Common (pin 6) for normal usage or the positive side (+Output, pin 3) to effectively reverse the output polarity. Filtering and Noise Reduction All UWR 5 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 low-ESR, tantalum or electrolytic capacitors across the input and/or output terminals. The capacitors should be located as close to the power converters as possible. Typical values are listed below. In many applications, using values greater than those listed will yield better results.

Pin Material
These power converters require a minimum 20% 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 input/output filtering can be recommended and perhaps added internally upon request. Contact DATEL Applications Engineering for details. Units can be screened or modified for higher guaranteed isolation voltages. Contact DATEL Applications Engineering for details. Units can be warranted or screened for lower-temperature operation. Contact DATEL Applications Engineering for details.
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. Input Fusing Cer tain applications and/or safety agencies may require the installation of fuses at the inputs of power conversion components. For DATEL UWR 5 Watt DC/DC Converters, you should use slow-blow type fuses with values no greater than 0.5A.
