The LT4180 maintains a tight regulation at the load over highly resistive cables. It is compatible with any conversion topology and can operate over an input voltage ranging from 3.1V to 50V and can produce an output voltage from 1.22V to 50V. There is a 5mA sink output that is powerful enough to drive an optocoupler. Additional features include a programmable fixed dither frequency or spread spectrum frequency, along with soft-start.
