I'm currently making a laser driver for rgb laser array and need some help. the array is a numm34, with basically 3 individual constant current control needs. I Can't find a topology compact enough to boost 9 - 12.6v to 28v, 30v and 30v at 3a, 2.1a and 3a. I could put the red and blue in series but then i wouldnt know what to do with the blue. any help?
