The proven cost-effectiveness, quality and long-term reliability that has come to define DATEL's standard, 3W, single-output, DIP-packaged DC/DC converters (see UST 3W Models) is now available in the "other standard pinout" (see next page) made popular by off-shore suppliers. These newly designed UWP Models exploit totally automated SMT assembly techniques and do not contain any trimpots, "wet" aluminum electrolytic capacitors, or manually soldered "flying" leads. Their made-in-the-USA quality and affordable pricing are rapidly making them the converters of choice in many existing applications. UWP DC/DC converters bring true component-like convenience to designers of modern distributed power systems. Exploiting an efficient, high-frequency (170-200kHz), flyback topology and high-density SMT assembly techniques, UWP DC/DC's have enough space to include input (pi type) and output filters within their package. They are fully isolated (500Vdc guaranteed) and do not require any external components to meet published specifications. They operate, without derating, over the full 40 to +75°C temperature range. 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). Output transient response time is a quick 200µsec, and output ripple and noise are typically 75mVp-p. All models are certified to UL1950, CSA 22.2 No. 950 and IEC950. Full EMI/EMC characterizations are currently in progress. DATEL's UWP 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 negative side (Output, pins 10 and 15) for normal usage or the positive side (+Output, pins 11 and 14) to effectively reverse the output polarity. Filtering and Noise Reduction All UWP 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 inter nally 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 or see DATEL's UST 3W DC/DC's for guaranteed 1000Vdc isolation.
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.
