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

UWR-3.3/4850-D48A (18-75V input, curve A) and UWR-3.3/4850-D12A (9-36V input, curve A) will derate curve AA if used over the limited input ranges of 20-60V or 10-30V, respectively. 2. "D48A" models (18-75V input ranges) that derate along curve B will derate along curve BB if used over the more limited input range of 24-60V. Notes: For "D5A" and "D12A" models, the case is connected to pin 2 (–VIN). For "D48A" and "D48E" models, the case is connected to pin 1 (+VIN).
