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.
