The LM3420 looks to be a good solution. For use with a 3S battery do you need to order the -12.6 version of…
Other Parts Discussed in Thread: LM3420 i want to build a charger to charge two 18650 batteries connected in series with 2600mAh
these two 18650 batteries feed a DC-DC-buck which then feeds 3.3v to circuit.
I want to use the following circuit from the datasheet…
