Is anyone aware of a pre-existing schematic/plan/diagram for a circuit that both boosts the voltage of a single lithium ion cell, and incorporates an LM317 for current regulation?
I'm not terribly familiar with voltage boosting circuits, but I did some searching on Digikey, and came up with the LD29300XX80
http://www.st.com/stonline/products/literature/ds/9248/ld29300xx18.pdf
- Output current up to 3A
- Output voltage fixed @ 8V
- Available in TO-220 package (IE, easy to work with, not SMD)
It seems to me that this IC could be integrated between a single 18650 and an LM317, for a workable single cell driver.
But are there already tested/known driver designs that use an LM317 with some sort of boost design to run off a single cell?
