DATEL's new A-Series switching DC/DC converters are designed to meet the demanding long-term-reliability and low-cost requirements of modern telecom, datacom, computer/networking and industrial-electronics applications. These highlyefficient, rugged devices combine straightforward circuit topologies, new components, proven SMT-on-pcb construction methods, and highly repeatable automatic-assembly techniques. The flexibility of the designs and their assembly methods readily permit minor modifications to optimize performance for specific applications. The single-output, 14-20 Watt Models of the A-Series deliver both high power densities and impressive MTBF's. Their superior durability is substantiated by a rigorous in-house qualification program including HALT (Highly Accelerated Life Testing), which is designed to detect any potential electrical, mechanical, or process weaknesses. Packaged in standard, 2" x 2" x 0.45", shielded metal cases with non-conductive coatings, these fully isolated (1500Vdc minimum) DC/DC's offer excellent line/load regulation, full I/O protection, thermal shutdown, and industry-standard pinouts. Output voltages include 3.3, 5, 5.2, 12 or 15 Volts. Input voltage ranges are DATEL's traditional ultra-wide 9-36V and 18-75V, as well as 4.7-7.5V. Each device provides remote on/off control and VOUT trim capability. All A-Series UWR models are fully EMI characterized and UL1950, CSA 950 and IEC 950 safety approved. A-Series DC/DC's are extremely reliable, easy-to-use, cost-effective power conver ters. Use them to improve the reliability of existing equipment or to develop new systems that exceed design objectives.

Notes: 1. The UWR-3.3/4850-D48A (18-75V input, curve A) and UWR-3.3/4850-D12A (9-36V input, curve A) will derate curve AA if used over the limited input ranges of 20-60V or 10-30V, respectively. 2. "D48A" models (18-75V input ranges) that derate along curve B will derate along curve BB if used over the more limited input range of 24-60V.

These are stress ratings. Exposure of devices to any of these conditions may adversely affect long-term reliability. Proper operation under conditions other than those listed in the Performance/Functional Specifications Table is not implied.

Floating Outputs Since these are isolated DC/DC converters, their outputs are "floating." Users may ground either the Common (pin 7) for normal usage or the positive side (+Output, pin 6) to effectively reverse the output polarity. Filtering and Noise Reduction All A-Series UWR 14-20 Watt DC/DC Converters achieve their rated ripple and noise specifications without the use of external input/output capacitors. In critical applications, input/output 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 below. In many applications, using values greater than those listed will yield better results.

These 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. Applying a voltage to the Control pin when no input power is applied to the converter can cause permanent damage to the converter. "D48A" models have BASIC, all other models have Functional insulation. Devices can be screened or modified for higher guaranteed isolation voltages. Contact DATEL Applications Engineering for details. Except for 3.3V outputs which have no protection.
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.
