These highly ef cient, rugged convert- Qual tested HALT tested EMC tested ers combine straightforward circuit topologies, the newest components, proven SMT-on-pcb Designed to meet UL/EN60950-1 construction methods, and highly repeatable automatic-assembly techniques. Their superior durability is substantiated by a rigorous in-house quali cation program that includes HALT Output voltages: 5, 12 or 15 Volts (Highly Accelerated Life Testing). Wide input voltage ranges: The wide input voltage ranges of these A-Series duals (4.7-7.25V forD5 models, 4.7-7.25V, 9-18V or 18-75V 9-18V forD12 models and 18-75V forD48 models) make them excellent candidates Small packages, 2 x 1 x 0.375 for battery-powered systems or for distributed power architectures. Their 5, 12 or 15 Volt Industry-standard pinouts outputs cover virtually all standard applications. These popular power converters are fully isolated (1500Vdc guaranteed) and display excel- Fully isolated, 1500Vdc guaranteed lent line and load regulation (0.3% max. for line and 1% max. for load). They are completely Guaranteed ef ciencies to 82% I/O protected (input overvoltage shutdown and reverse-polarity protection, output current limit- 40 to +100C operating temperature ing and overvoltage protection) and contain input (pi type) and output ltering to reduce noise. Modi cations and customs for OEMs They require no external components and offer trueplug-and-pla convenience. These extremely reliable, cost-effective power converters carry industry-standard pinouts Select models are RoHS compliant making them ideal replacements for other more costly, less reliable power converters in com- puter, telecom/datacom, instrumentation and ATE applications. They are an excellent choice for both new design-ins and upgrading older systems. +VIN +VOUT (1) (3) COMMON (4) VOUT VIN (5) (2) OPTO REFERENCE & PWM ISOLATION ERROR AMP CONTROLLER Typical topology is shown.
