TWR-5/3000-15/500-D48A-C

TWR A-Series www.murata-ps.com 20W, Triple Output DC-DC Converters Typical unit 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. FEATURES PRODUCT OVERVIEW  Low cost! Highly reliable! 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  Full 20 Watts output power  Power “user-allocated” among outputs  Proven SMT-on-pcb construction  Qual tested; HALT tested; EMC tested  Output voltages: +5V/±12V or +5V/±15V  Ultra-wide input voltage ranges: 9-36V or 18-75V  Designed to meet UL1950/EN60950. BASIC insulation (all 48VIN models)  CE mark available (75V input models)  Small packages, 2" x 2" x 0.45"  Fully isolated, 1500Vdc guaranteed  Guaranteed efficiencies to 82%  –40 to +100°C operating temperature  Modifications and customs for OEM’s 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.
