How to create a buck-boost converter with a low-voltage cutoff
I have seen a good one from pololu here but i going to do a single board circuit. I have tried looking for what IC pololu is using but i could not find it (i also doubt that they will tell me).


FWIW, it looks like they're using TPS63070.

It matches the Pololu description in several points:


Marked with "3070" like the device pictured on the Pololu website
Comes in a 2.5 x 3 mm QFN-like package
user defined under-voltage lockout
2 - 16 V input range
Unusual pin arrangement with 3 pins along one edge with 4 pins on the opposite edge
