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-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, 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 agency safety approved. A-Series DC/DC's are extremely reliable, easy-to-use, cost-effective power converters. Use them to improve the reliability of existing equipment or to develop new systems that exceed design objectives. +VOUT (3) +VIN (1) COMMON (5) Typical topology is shown -VIN (2) PWM CONTROLLER OPTO ISOLATION REFERENCE & ERROR AMP Figure 1.

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.

The five-pronged program draws our Quality Assurance function into all aspects of new-product design, development, characterization, qualification and manufacturing. Design for Reliability 80 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. To work from an approved components/vendors list ensuring the use of reliable components and the rigorous qualification of new components. 2. To design with safety margins by adhering to a strict set of derating guidelines and performing theoretical worst-case analyses. 3. To locate potential design weaknesses early in the product-development cycle by using extensive HALT (Highly Accelerated Life Testing). 4. To prove that early design improvements are effective by employing a thorough FRACA (Failure Reporting Analysis and Corrective Action) System. 70 60 Radiated Emissions (dBV/M) DATEL's world-class design, development and manufacturing team stands ready to work with you to deliver the exact power converter you need for your demanding, large volume, OEM applications.

We use HALT (Highly Accelerated Life Testing) repeatedly during the design and early manufacturing phases to detect potential electrical and mechanical design weaknesses that could result in possible future field failures. 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. During HALT, prototype and pre-production DC/DC converters 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 HALT 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 HALT tester capable 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 +125C, 30C/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 DATEL's new A-Series could not be made to fail prior to reaching either the limits of the HALT chamber or some previously known physical limit of the device. We also use the HALT chamber and its ability to rapidly cool devices to verify their "cold-start" capabilities. 100 40 80 20 40 20 0 0 Random Vibration (G's) Temperature (C) 60 Qualification Testing Qualification Test Method/Comments HALT DATEL in-house procedure High Temperature Storage Max. rated temp., 1,000 hours Thermal Shock 10 cycles, -55 to +125C Temperature/Humidity +85C, 85% humidity, 48 hours Lead Integrity DATEL in-house procedure Life Test +70C, 500 hours* Marking Permanency DATEL in-house procedure End Point Electrical Tests Per product specification * Interim electrical test at 200 hours. 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. -20 -40 10 20 30 40 50 60 70 80 90 Test Time (minutes) Typical HALT Profile Murata Power Solutions, Inc. 11 Cabot Boulevard, Mansfield, MA 02048-1151 U.S.A.
