I’ve been looking at the LTC3868 for a buck converter design from 12v to 8v to charge 3 supercapacitors in series at 70A. I can’t seem to find a feature to lower current as the capacitors reach the desired voltage. I have the SABMOSFET to balance and protect from Over Voltage. I was hoping to use PLLIN/MODE pin to select between Burst mode, Force continuous and pulse-skipping modes to limit the charge current. Would this be a good idea and is it ok do this on-the-fly?
