I am having some issues making my boost converter (TPS61085PWR) output the correct amount of current to 3 LEDs connected in series. I am using a 600 mAh 3.6 V lipo battery to power the circuit. When the circuit is being powered from 3.6 V, the boost converter is outputting ~11.5 V, and the LED's are consuming ~0.011 A. When I increased the input voltage to 7.6 V, the boost converter outputs ~11.6 V, but the current goes up to 0.09 A (where it should be). I am running this IC at 650 kHz.
If anyone could give me some insight to this issue I would be forever grateful!
