PRODUCT OVERVIEW
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 protec-
tion, and output overvoltage clamping to protect
both the power converters and their loads.
As members of Murata Power Solutions' new
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 construc-
tion 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 cur-
rents as high as ±210mA). These devices were
designed to power small analog/digital partitions in
equipment employing distributed-power archi-
tectures with bus voltages between 4.7 and 72
Volts. Applications include computer/networking,
telecom/datacom equipment, industrial instrumen-
tation and automatic test equipment.
