You asked the right person. I recommend the following boost ICs to you. These are all ICs dedicated to LED drivers. The AP3015A has an operating voltage of 1.0 ~ 12V (note: the minimum operating voltage without the A suffix is 1.2). v). UM3433 is the lowest. The operating voltage is 0.9 V. The TL499 is also good, but it is expensive. About 8 yuan/piece.
