[chbot] Boost converter with constant current output

[Mark Atherton]

take a look at the small LCD-LED backlight invertor class of part

I have used the TPS61165 at 22V, 80mA, and input goes gown to 3V.

Output current is set by one resistor.

Datasheet shows examples down to 12V out

Digikey have them in stock, as do E14 and RS
