UWR Series www.murata-ps.com Single Output, High Reliability, 2 x 2 , 14-20 Watt, DC/DC Converters Typical units FEATURES PRODUCT OVERVIEW Low cost Highly reliable Murata Power Solutions new A-Series switching DC/DC converters are designed to meet the Proven SMT-on-pcb construction demanding long-term-reliability and low-cost requirements of modern telecom, datacom, computer/ networking and industrial-electronics applications. These highly-ef cient, rugged devices combine Designed to meet UL/ EN60950, straightforward circuit topologies, new components, proven SMT-on-pcb construction methods, and BASIC insulation (D48A models) highly repeatable automatic-assembly techniques. The exibility of the designs and their assembly mark available (48VIN models) methods readily permit minor modi cations to optimize performance for speci c applications. The single-output, 14-20 Watt Models of the A-Series deliver both high power densities and Output voltages: 3.3/5/5.2/12/15 Volts impressive MTBFs. Ultra-wide input voltage ranges:4.7-7.5V, 9-36V Packaged in standard, 2 x 2 x 0.45 , shielded metal cases with non-conductive coatings, these or 18-75V fully isolated (1500Vdc minimum) DC/DCs offer excellent line/load regulation, full I/O protection, Small packages, 2 x 2 x 0.45 thermal shutdown, and industry-standard pinouts. Output voltages include 3.3, 5, 5.2, 12 or 15 Volts. Input voltage ranges are Murata Power Solu- Industry-standard pinouts tions traditional ultra-wide 9-36V and 18-75V, as well as 4.7-7.5V. Each device provides remote on/ Fully isolated, 1500Vdc guaranteed off control and VOUT trim capability. All A-Series UWR models are fully EMI characterized and designed Guaranteed ef ciencies to 84% to meet UL1950, CSA 950 and IEC 950 safety. A-Series DC/DCs are extremely reliable, easy-to-use, cost-effective power converters. Use them 40 to +100C operating temperature to improve the reliability of existing equipment or to develop Modi cations and customs for OEMs new systems that exceed design objectives. +VIN +VOUT (6) (1) COMMON (7) VIN (2) +VOUT OPTO ON/OFF PWM REFERENCE & ISOLATION TRIM CONTROL CONTROLLER ERROR AMP (4) (8) Typical topology is shown.
