TWR A-Series www.murata-ps.com 20W, Triple Output DC-DC Converters Among the three families of triple-output DC/DC converters in MPSs A-Series, the 20W 2 x 2 devices are distinguished by their unique power-sharing architecture. This feature enables devices to deliver Typical unit the full 20 Watts of output power under a variety of output-loading conditions. FEATURES PRODUCT OVERVIEW Each units primary +5V output can source any cur- durability is substantiated by a rigorous in-house Low cost Highly reliable rent up to 3 Amps (primary power = 15W) while its quali cation program that includes HALT (Highly Full 20 Watts output power auxiliary 12/15V outputs can source currents up to Accelerated Life Testing). Power user-allocated among outputs 500mA (auxiliary power = 12/15W). Devices deliver Each device has a +5V primary output and either any combination of primary plus auxiliary power as 12V or 15V auxiliary outputs. D12A models Proven SMT-on-pcb construction long as the total output power does not exceed 20 achieve fully rated performance with inputs ranging Qual tested HALT tested EMC tested Watts.
