I would like to use the LTC3122 boost converter in an application where I need a variable voltage level between 5 and 12V. The input voltage will be between 1.8V and 4.2V. I was thinking of placing a Maxim MAX5419 digital potentiometer in the R2 position of the feedback network (FB pin to ground). Do you see any issues with this setup? I plan to disable the device by pulling SD low during the time when the potentiometer will be adjusted.
Thanks for your help -
