Triple Output
A-Series, TWR Models
Among the three families of triple-output DC/DC converters in DATEL’s new
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. Each unit’s primary +5V output can
source any current 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 requirements.
As members of DATEL’s new A-Series, the 20W triples exhibit both low cost and
outstanding long-term reliability. Their design combines straightforward circuit topolo-
gies, 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 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 over-
voltage shutdown, input reverse-polarity protection, and output overvoltage clamping
to protect both the power converters and their loads.
