Hello, I have a high power RGB LED with common anode. I want to have 3 of them in series, and put them on 15V power supply. And I want to switch green color on, and red color as well (something like a normal traffic light) Here is the problem: Given that three LEDs are in series, and are common anode, how can I switch color separately? I was thinking about placing 6 transistors between them (on cathode of each LED - e.g. 1LED= 2 transistors for each color). I assume P-channel MOSFET (i.e. IRF9250) can do the job? However, this is quite bad solution, does anyone have anything better? I hope I explained it well, I will post a drawing later on. Thank you in advance, M.
