Modications and customs for OEM’s
Each unit’s primary +5V output can source any cur-
rent up to 3 Amps (primary power = 15W); while its
auxiliary ±12/15V outputs can source currents up to
±500mA (auxiliary power = 12/15W). Devices deliver
any combination of primary plus auxiliary power as
long as the total output power does not exceed 20
Watts. This feature enables designers to select a
single device to fulll any number of different require-
ments.
As members of MPS’s new A-Series, the 20W triples
exhibit 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 repeat-
able automatic-assembly techniques. Their superior
durability is substantiated by a rigorous in-house
qualication program that includes HALT (Highly
Accelerated Life Testing).
Each device has a +5V primary output and either
±12V or ±15V auxiliary outputs. “D12A” models
achieve fully rated performance with inputs ranging
from 9 to 36 Volts. “D48A” models operate over an
input range of 18-75 Volts.
These full-featured 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.
SIMPLIFIED SCHEMATIC
PRODUCT OVERVIEW
Among the three families of triple-output DC/DC converters in MPS’s
A-Series, the 20W 2" x 2" devices are distinguished by their unique
“power-sharing” architecture. This feature enables devices to deliver
the full 20 Watts of output power under a variety of output-loading
conditions.
