PRODUCT OVERVIEW

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 MPS’s new A-Series DC/DC converters. These highly efficient, rugged convert-

ers 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 excel-

lent 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 limit-

ing 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 com-

puter, telecom/datacom, instrumentation and ATE applications. They are an excellent choice for

both new design-ins and upgrading older systems.
