4.7-7.25V, 9-18V or 18-75V
It’s 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 C&D’s new A-Series DC/DC converters. These highly
efficient, rugged converters combine straightforward circuit topologies, the newest
components, proven SMT-on-pcb construction methods, and highly repeatable automatic-assembly techniques. Their superior durability is substantiated by a rigorous
in-house qualification 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 18-75V for "D48A" models) make them excellent candidates for battery-powered systems or for distributed power architectures.
Their ±5, ±12 or ±15 Volt outputs cover virtually all standard applications.
These popular power converters are fully isolated (1500Vdc guaranteed) and
display excellent line and load regulation (±0.3% max. for line and ±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 filtering 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.
