15-20W, Dual Output DC/DC Converters
PRODUCT OVERVIEW
FEATURES
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
Low cost! Highly reliable!
Proven SMT-on-pcb construction
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).
Qual tested; HALT tested; EMC tested
Designed to meet UL/ EN60950-1,
BASIC insulation (48VIN models)

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.
Output voltages: 5, 1ꢀ or 15 Volts
Ultra-wide input voltage ranges:
4.7-7.5V, 9-36V or 18-75V
These popular power converters are fully isolated (1500Vdc guaranteed) and display excellent
line and load regulation (with specs as low as 0.3ꢀ max. for line and 0.5ꢀ 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.
