Figure 1. Simplified Schematic
Placing reliability and cost considerations above all others, D A TEL’ 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-term-reliability requirements of today’ s telecom, datacom and computer/networking applications, the A-Series may well be the most cost-effectiv e DC/DC’s av ailable 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 HAL T (Highly Accelerated Life T esting). The goal of HAL T is not to simulate field conditions but to e xpose 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 off er excellent line/load regulation, full I/O protection, thermal shutdown, and industry-standard pinouts.
Output voltages include 5, 5.2, 12 and 15 V olts. Input voltage ranges are either 4.7-
7.25V ("D5A" models), 9-18V ("D12A" models) or 18-72V ("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 reliab le, easy-to-use, cost-eff ective power converters. Use them to improve the reliability of existing equipment or to develop new systems that exceed design objectives.

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 g reater than those listed will yield better results.

If you’re designing with EMC in mind, please note that all of D ATEL’s A-Series UWR 6-10 Watt DC/DC Converters have been characterized for radiated and conducted emissions in our new EMI/EMC laboratory. Testing is conducted in an EMCO 5305 GTEM test cell utilizing EMCO automated EMC test software. Radiated emissions are tested to the limits of FCC Part 15, Class B and CISPR 22 (EN 55022), Class B. Correlation to other specifica­tions can be supplied upon request. Radiated emissions plots to FCC and CISPR 22 for model UWR-12/665-D5A appear below. Published EMC test reports are available for each model number. Contact DATEL’s Applications Engineering Department for more details.

Quality and Reliability
The A-Series are the first DC/DC Converters to emerge from DATEL ’ s ne w, company-wide approach to designing and manufacturing the most reliable power converters available. The five-pronged program draws our Quality Assurance function into all aspects of new-product design, development, characterization, qualification and manufacturing.
Design for Reliability
Design for Reliability is woven throughout our multi-phased, new-product­development process. Design-for-reliability practices are fully documented and begin early in the new-product development cycle with the following goals:
1. T o work from an approved components/v endors list ensuring the use of reliable components and the rigorous qualification of new components.
2. To design with saf ety margins by adhering to a strict set of derating guidelines and performing theoretical worst-case analyses.
3. T o locate potential design weaknesses early in the product-development cycle by using extensiv e HAL T (Highly Accelerated Lif e Testing).
4. To prov e that early design improvements are effectiv e by emplo ying a thorough FRACA (Failure Reporting Analysis and Corrective Action) system.
HAL T T esting
The goal of the accelerated-stress techniques used by D A TEL is to f orce device maturity , in a short period of time, by exposing de vices to excessive le vels of "every stimulus of potential value ." We use HALT (Highly Accelerated Life T esting) repeatedly during the design and early manufacturing phases to detect potential electrical and mechanical design weaknesses that could result in possible future field failures.
During HAL T , prototype and pre-production DC/DC con verters are subjected to progressively higher stress levels induced by thermal cycling, rate of tempera­ture change, vibration, power cycling, product-specific stresses (such as dc voltage variation) and combined environments. The stresses are not meant to simulate field environments but to expose any weaknesses in a product’s electro/mechanical design and/or assembly processes. The goal of HAL T is to make products fail so that device weaknesses can be analyzed and strength­ened as appropriate. Applied stresses are continually stepped up until products eventually fail. After corrective actions and/or design changes, stresses are stepped up again and the cycle is repeated until the "fundamental limit of the
technology" is determined. DATEL has invested in a Qualmark OVS-1 HAL T tester capab le of applying
voltage and temperature extremes as well as 6-axis, linear and rotational, random vibration. A typical HALT profile (shown above) consists of thermal cycling (–55 to +125°C, 30°C/minute) and simultaneous, gradually increasing, random longitudinal and rotational vibration up to 20G’s with load cycling and applied-voltage extremes added as desired. Many devices in D A TEL’s ne w A­Series could not be made to fail prior to reaching either the limits of the HAL T chamber or some previously known physical limit of the device. We also use the HAL T chamber and its ability to rapidly cool devices to v erify their "cold­start" capabilities.
Qualification
For each new product, electrical performance is verified via a comprehensive characterization process and long-term reliability is confirmed via a rigorous qualification procedure. The qual procedure includes such strenuous tests as thermal shock and 500 hour life. Qual testing is summarized below .
In-Line Process Controls and Screening
A combination of statistical sampling and 100% inspection techniques keeps our assembly line under constant control. Parameters such as solder-paste thickness, component placement, cleanliness, etc. are statistically sampled, charted and fine tuned as necessary . Visual inspections are performed by trained operators after pick-and-place, soldering and cleaning operations. Units are 100% electrically tested prior to potting. All devices are temperature cycled, burned-in, hi-pot tested and final-electrical tested prior to external visual examination, packing and shipping.
Rapid Response to Problems
DATEL employs an outstanding corrective-action system to immediately address any detected shortcomings in either products or processes. Whenever our assembly , quality or engineering personnel spot a product/process problem, or if a product is returned with a potential defect, we immediately perform a detailed failure analysis and, if necessary , undertake corrective actions. Over time, this system has helped refine our assembly operation to yield one of the lowest product defect rates in the industry .
