The TWR-5/3000-15/500-D12A-C is a 3-output board-mount fully-isolated DC to DC Converter with outstanding long-term high-reliability. The TWR A-series 20W 2 x 2-inch device is distinguished by its unique "power-sharing" architecture. It delivers any combination of primary plus auxiliary power as long as the total output power does not exceed 20W. This feature enables designers to select a single device to fulfill any number of different requirements. Its design combines straightforward circuit topologies, the newest components, proven SMT-on-PCB construction methods and highly repeatable automatic-assembly techniques. The superior durability is substantiated by a rigorous in-house qualification program that includes HALT (Highly Accelerated Life Testing). 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.
