I have a design which will include the optional use case of boosting up to 7V from a li-ion battery. I can't seem to find any drivers dedicated to li-ion for this? There seem to be a few buck boost that can generate 3V3. Should I use that 3V3 and boost using a standard boost converter? The Li-ion battery is also going straight into an IC which includes li-ion charge and protection circuitry.
I know this is wasteful use of the battery but will only be used if the user sets the jumper in that position as an additional (but limited) design feature.
