PRODUCT OVERVIEW
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 MPS’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 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 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 (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-stan-
dard pinouts and are ideally suited for high-volume computer, telecom/datacom, instrumentation and
ATE applications.
