BWR Models www.murata-ps.com 15-20W, Dual Output DC/DC Converters PRODUCT OVERVIEW FEATURES Low cost Highly reliable For your mid-range power requirements, its hard to beat the combination of low cost, proven reliability and outstanding electrical performance offered by the Proven SMT-on-pcb construction 15-20W, dual-output models of MPSs new A-Series DC/DC converters. These highly ef cient, rugged Qual tested HALT tested EMC tested converters combine straightforward circuit topologies, the newest components, proven SMT-on- Designed to meet UL/ EN60950-1, pcb construction methods, and highly repeatable automatic-assembly techniques. Their superior BASIC insulation (48VIN models) durability is substantiated by a rigorous in-house quali cation program that includes HALT (Highly Accelerated Life Testing). mark available (48VIN models) The ultra-wide input voltage ranges of the A-Series duals (4.7-7.5V forD5 models, 9-36V Output voltages: 5, 12 or 15 Volts forD12 models and 18-75V forD48 models) make them excellent candidates for battery- Ultra-wide input voltage ranges: powered systems or for distributed power architectures. Their 5, 12 or 15 Volt outputs cover virtually all standard applications. 4.7-7.5V, 9-36V or 18-75V These popular power converters are fully isolated (1500Vdc guaranteed) and display excellent Small packages, 2 x 2 x 0.45 line and load regulation (with specs as low as 0.3% max. for line and 0.5% max. for load). They Industry-standard pinouts are completely I/O protected (input overvoltage shutdown and reverse-polarity protection, output current limiting and overvoltage protection) and contain input (pi type) and output ltering to reduce Fully isolated, 1500Vdc guaranteed noise. They require no external components and offer trueplug-and-pla convenience. Guaranteed ef ciencies to 82% These extremely reliable, cost-effective power converters are housed in standard 2 x 2 x 40 to +100C operating temperature 0.45 metal packages coated with electrically non-conductive materials. They offer industry-stan- Modi cations and customs for OEMs dard pinouts and are ideally suited for high-volume computer, telecom/datacom, instrumentation and ATE applications. +VIN +VOUT (5) (1) COMMON (6) VIN VOUT (2) (7) ON/OFF PWM OPTO REFERENCE & TRIM CONTROL CONTROLLER ISOLATION ERROR AMP (8) (4) Typical topology is shown.
