The 1500UFR series is a family of 16 models DC/DC

converters designed to address the application needs for

data communication equipment, mobile battery driven equip-

ment, distributed power systems, telecommunications

equipment, mixed analog/ digital subsystems, process/

machine control equipment, computer peripheral systems

and industrial robot systems. In addition to packing up to 15

watts of power into a 2” X 1” X 0.4” package with efficiency up

to 86%, the series also has ultra-wide input ranges of 9-36VDC

and 18-75 VDC, which are available in output voltage of 3.3V, 5V,

5.1V, 12V, 15V, ±5V, ±12V and ±15 VDC.
