I might get flamed to death for this, but google is turning up nothing. Because reasons, I want to be able to charge my phone off a greenworks 80V battery. The LM317 seemed obvious, but it's max differential is 40V. Anyway, I tried googling for something that'll deal with an 80V spread and run 2100 ma.
If anyone has any suggestions, I'd love to hear them. It's been a long time since I did analog circuits and I was bad at it then too.
Thanks
