Proven SMT-on-pcb construction Designed to meet UL1950 and EN60950 Qual tested; HALT tested; EMC tested Small packages, 2" x 1" x 0.375" Standard pinouts 5, 5.2, 12 or 15 Volt outputs Choice of 3 wide-range inputs: 4.7-7.25 Volts 9-18 Volts 18-75 Volts Fully isolated, 1500Vdc guaranteed 40 to +100°C operation 5-side metal shielded cases with non-conductive baseplates Modifications and customs for OEM's
Placing reliability and cost considerations above all others, DATEL's new A-Series DC/DC Converters combine straightforward circuit topologies, the newest components, proven SMT-on-pcb construction, and highly repeatable automatic assembly techniques. Considering the critical low-cost and long-termreliability requirements of today's telecom, datacom and computer/networking applications, the A-Series may well be the most cost-effective DC/DC's available today. The single-output, 6-10 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). The goal of HALT is not to simulate field conditions but to expose devices to multiple excessive stresses with the intention of precipitating any potential electrical, mechanical or process weaknesses. Packaged in 2" x 1" x 0.375" shielded metal cases with non-conductive coatings, these fully isolated (1500Vdc guaranteed) DC/DC's offer excellent line/load regulation, full I/O protection, thermal shutdown, and industry-standard pinouts. Output voltages include 5, 5.2, 12 and 15 Volts. Input voltage ranges are either 4.7-7.25V ("D5A" models), 9-18V ("D12A" models) or 18-75V ("D48A" models). All A-Series UWR models are fully EMI characterized and UL1950, CSA950 and IEC950 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.

TECHNICAL NOTES
Floating Outputs Since these are isolated DC/DC converters, their outputs are "floating." Designers will usually use the output Common (pin 5) as the ground/return of the load circuit. You can, however, use the +Output (pin 3) as ground/return to effectively reverse the output polarity. Filtering and Noise Reduction All A-Series UWR 6-10 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 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. Except for 3.3V devices 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.
