High-Reliability, 2" x 2"
15-20 Watt, DC/DC Conver ters
For your mid-range pow er 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 D A TEL’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 HAL T (Highly Accelerated Lif e 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 V olt outputs cov er 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. f or load). They are completely I/O protected (input ov ervoltage 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. The y
offer industry-standard pinouts and are ideally suited for high-volume computer ,
telecom/datacom, instrumentation and A TE applications.
