These devices each have a primary +5V output
that can source from 1 Amp to 1.5 Amps (model
dependent) and auxiliary ±12/15V outputs that can
source from ±150 to ±250mA (model dependent).
All models can simultaneously source maximum
rated current from both primary and auxiliary
outputs. The nominal input voltage for each model
is 48V.
As members of Murata Power Solutions’ new
A-Series, the 12-15W triples exhibit both low cost
and outstanding long-term reliability. Their design
combines straightforward circuit topologies, proven
SMT-on-pcb construction methods, the newest
components, and highly repeatable automatic-
assembly techniques. The A-Series TWR’s superior
durability is substantiated by a rigorous in-house
qualication program that includes HALT (Highly-
Accelerated Life Testing), which is designed to
detect any potential electrical, mechanical or proc-
ess weakness.
Packaged in standard, 2" x 2" x 0.45", shielded
metal cases with non-conductive coatings, these
fully isolated (1000Vdc minimum) DC/DC’s offer
excellent line and load regulation. Additionally,
these A-Series triples have non-latching output
current limiting, input overvoltage shutdown, input
reverse-polarity protection, and output overvoltage
clamping to protect both the power converters and
their loads. All A-Series TWR models are fully EMI
characterized and designed to meet UL1950, IEC
950, CSA 950 and EN60950.
SIMPLIFIED SCHEMATIC
Featuring Murata Power Solutions' ultra-wide, 18-72V, input voltage
range, this Family of A-Series, TWR (triple-output) DC/DC converters
deliver up to 15 Watts.
