Typical topology is shown.

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 efﬁ cient, 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 qualiﬁ cation 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 ﬁ ltering 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.

BWR Models 15-20W, Dual Output DC/DC Converters MPS has invested in a Qualmark OVS-1 HALT tester capable of applying voltage and temperature extremes as well as 6-axis, linear and rotational, random vibration. A typical HALT profile (shown above) consists of thermal cycling (–55 to +125°C, 30°C/minute) and simultaneous, gradually increasing, random longitudinal and rotational vibration up to 20G’s with load cycling and applied-voltage extremes added as desired.
