It鈥檚 hard to beat the combination of low cost, small size (standard 2" x 1" x 0.375"
package) proven reliability and outstanding electrical performance offered by the
7-10W, dual-output models of DATEL鈥檚 new A-Series DC/DC converters. These highly
ef鏗乧ient, rugged converters combine straightforward circuit topologies, the newest
components, proven SMT-on-pcb construction methods, and highly repeatable auto-
matic-assembly techniques. Their superior durability is substantiated by a rigorous
in-house quali鏗乧ation program that includes HALT (Highly Accelerated Life Testing).
The wide input voltage ranges of these A-Series duals (4.7-7.25V for "D5A"
models, 9-18V for "D12A" models and 18-72V for "D48A" models) make them excel-
lent candidates for battery-powered systems or for distributed power architectures.
Their 鹵5, 鹵12 or 鹵15 Volt outputs cover virtually all standard applications.
These popular power converters are fully isolated (1500Vdc guaranteed) and
display excellent line and load regulation (鹵0.3% max. for line and 鹵1% max. for load).
They are completely I/O protected (input overvoltage shutdown and reverse-polarity
protection, output current limiting and overvoltage protection) and contain input (pi
type) and output 鏗乴tering to reduce noise. They require no external components and
offer true "plug-and-play" convenience.
These extremely reliable, cost-effective power converters carry industry-standard
pinouts making them ideal replacements for other more costly, less reliable power
converters in computer, telecom/datacom, instrumentation and ATE applications.
They are an excellent choice for both new design-ins and upgrading older systems.
