It's hard beat combination cost, small size (standard 0.375" package) proven reliability outstanding electrical performance offered 7-10W, dual-output models DATEL's A-Series DC/DC converters. These highly efficient, rugged converters combine straightforward circuit topologies, newest components, proven SMT-on-pcb construction methods, highly repeatable automatic-assembly techniques. Their superior durability substantiated rigorous in-house qualification program that includes HALT (Highly Accelerated Life Testing). wide input voltage ranges these A-Series duals (4.7-7.25V "D5A" models, 9-18V "D12A" models 18-72V "D48A" models) make them excellent candidates battery-powered systems distributed power architectures. Their Volt outputs cover virtually standard applications. These popular power converters fully isolated (1500Vdc guaranteed) display excellent line load regulation (±0.3% max. line max. load). They completely protected (input overvoltage shutdown reverse-polarity protection, output current limiting overvoltage protection) contain input type) output filtering reduce noise. They require external components offer true "plug-and-play" convenience. These extremely reliable, cost-effective power converters carry industry-standard pinouts making them ideal replacements other more costly, less reliable power converters computer, telecom/datacom, instrumentation applications.

Quality Reliability
A-Series first DC/DC Converters emerge from DATEL's new, company-wide approach designing manufacturing most reliable power converters available. five-pronged program draws Quality Assurance function into aspects new-product design, development, characterization, qualification manufacturing. Design Reliability Design Reliability woven throughout multi-phased, new-productdevelopment process. Design-for-reliability practices fully documented begin early new-product development cycle with following goals: work from approved components/vendors list ensuring reliable components rigorous qualification components. design with safety margins adhering strict derating guidelines performing theoretical worst-case analyses. locate potential design weaknesses early product-development cycle using extensive HALT (Highly Accelerated Life Testing). prove that early design improvements effective employing thorough FRACA (Failure Reporting Analysis Corrective Action) system. HALT Testing goal accelerated-stress techniques used DATEL force device maturity, short period time, exposing devices excessive levels "every stimulus potential value." HALT (Highly Accelerated Life Testing) repeatedly during design early manufacturing phases detect potential electrical mechanical design weaknesses that could result possible future field failures. During HALT, prototype pre-production DC/DC converters subjected progressively higher stress levels induced thermal cycling, rate temperature change, vibration, power cycling, product-specific stresses (such voltage variation) combined environments. stresses meant simulate field environments expose weaknesses product's electro/mechanical design and/or assembly processes. goal HALT make products fail that device weaknesses analyzed strengthened appropriate.
