1500UR Series SINGLE/DUAL OUTPUT DC/DC CONVERTERS   DESCRIPTION        The 1500UR series is a family of miniature 15W DC/DC converters specifically designed for board mount power distribution applications where space is critical, but performance and power cannot be sacrificed. Standard features include an ultra-wide 4:1 input voltage range, efficiency as high as 83% and continuous short circuit protection by input current limiting. 14 models operate from (4:1) input voltage ranges of 10 to 40 VDC or 18 to 72 VDC and provide tightly regulated outputs of 3.3, 5, 12, 15, ±5, ±12 or ±15 VDC. All models are packaged in a compact, low profile 2” X 2” X 0.4” metal case.
