Among the three families of triple-output DC/DC converters in Murata Power Solutions' new A-Series, the 8-11W, 2" x 1" devices 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 non-latching 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 Murata Power Solutionsnew A-Series, the 8-11W triples feature both low cost and outstanding long-term reliability. Their design combines 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).

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 Volts.
