Features

Among the three families of triple-output DC/DC converters in DATEL’s new
A-Series, the 8-11W, 2" x 1" de vices stand out as the industry’s smallest
full-featured triples. Housed in miniature 2" x 1" x 0.375", 5-side shielded, metal
packages with electrically non-conductive coatings, these power converters offer non­latching output current limiting, input overvoltage shutdown (except D5A models), input
reverse-polarity protection, and output overvoltage clamping to protect both the power
converters and their loads.

As members of DATEL ’ s new A-Series, the 8-11W triples feature both lo w cost and
outstanding long-term reliability. Their design combines straightforw ard circuit topolo­gies, the newest components, pro ven 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
T esting).

Each of these fully line and load-regulated switching DC/DC converters has a +5V
primary output (with output current as high as 1A) and either ±12V or ±15V auxiliary
outputs (with currents as high as ±210mA). These devices were designed to power
small analog/digital partitions in equipment employing distributed-power architectures
with bus voltages between 4.7 and 72 V olts. Applications include computer/networking,
telecom/datacom equipment, industrial instrumentation and automatic test equipment.
