20W, Triple Output DC/DC Converter | Murata-PS

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 fulfill any number of different requirements.

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 repeatable automatic-assembly techniques. Their superior durability is substantiated by a rigorous in-house qualification 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.
