Power RGB LED Controller is the extension of tiny RGB to drive high power LEDís. For this project I used a 3 x 1W common Anode RGB LED. Q1 to Q3 are N-Channel HEXFet Mosfetís with logic level drive and a RDSon at about 50mOhms. R1 to R3 are at about 2k2, R4 to R6 at about 15k and R7 to R9 depend on the LED used and VCC. If you use FETís with higher RDSon you have to consider RDS in your calculation!
