Quick one here tearing down one of these outdoor solar lights. The batteries in the set I bought are loosing their max capacity, so starting to think about upgrading these a bit :)
Sorry about the quick off-the-cuff description of how that boost converter works... there's obviously a lot more to it than that and this might be current regulated as well, but this video gets through the basics at least. And keep in mind that I made this video live while I was measuring things and skimming the datasheet.
Here's the datasheet for that custom ASIC:

Thanks to all the Patrons for dropping a few bucks in the tip jar to help make these videos happen!
