Buck and Boost Drivers, Testing, Modding, and Discussion (Pic Heavy)

Wow that MP3431 datasheet shows 97% efficiency @1A which is around the current I need. Just need a driver with more evenly-spaced or configurable modes, and a ~3V cutoff voltage.

EDIT: Appears to be PWM not constant current :person_facepalming:

I thought that driver was 12v out only, not 6v.

Have you seen Loneoceans boost driver? He does not sell them, he just designed it and shows others how to assemble the parts.
