Hey all, in my never ending quest to find boost driver alternatives until the flex's are back in stock, i've stumbled upon a very nice driver capable of running a LOC with 1 li-ion battery and a diode in between.
Driver is here
its says its a 1.5V - 4.2V boost driver
when attached to a test load set for red and an additional diode in between the driver and the test load, i was measuring 520mA. thats right about the highest to run a LOC with decent life.
i couldnt help myself so i bought an LG 22x dvd burner (only 15 bucks at a local shop here) and I built a pocket red build. works great, lpm's at 290~300mW.
It seems like a constant current design. why I say this is because using my regulated power supply with adjustable current and voltage, I set current to max, and then slowly ramped up the voltage. between 3.2V all the way up to 4.15V the current stayed the same at 520mA. below that it had to boost a bit more and current was slightly lower. from 1.5V it was at 350mA.
I dont reeally care for all that "LED drivers are bad" crap, this driver is a winner for LOC's in my book.
