Are there chips doing that but buck-boost ? I know there are for "normal" current range, but I haven't found anything super low power
Use case: I want to just have a solar panel + supercap into microcontroller for IoT stuff so I want to suck that cap dry and avoid batteries for temperature range reasons.
Oh, wow, it's even in stock, thanks. I was looking for something like that some time ago but back then only BQ25570 really fitted (and was overkill and a bit more pricy for that)
