For your mid-range power requirements, it’s hard to beat the combination of low
cost, proven reliability and outstanding electrical performance offered by the
15-20W, 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 repeat-
able automatic-assembly techniques. Their superior durability is substantiated by a
rigorous in-house qualification program that includes HALT (Highly Accelerated Life
Testing).
The ultra-wide input voltage ranges of the A-Series duals (4.7-7.5V for "D5A"
models, 9-36V for "D12A" models and 18-75V for "D48A" models) make them excel-
lent 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 (with specs as low as ±0.3% max. for
line and ±0.5% 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 are housed in standard
2" x 2" x 0.45" metal packages coated with electrically non-conductive materials.
They offer industry-standard pinouts and are ideally suited for high-volume com-
puter, telecom/datacom, instrumentation and ATE applications.
