Hi all. First off, I do not have a schematic handy. I have a circuit with 6v DC powering a 555 and 4017. I have purchased some 10w leds. They are tri colour RGB. Red has an operating voltage of 6v. Blue and Green both need 11v. LED Specs are:
Red 120-150 lumens, Green 200-300 lumens, Blue 70-100 lumens
- Vf: Red 6-8V, Green 9-12V, Blue 9-12V
- Emitting angle: 140 degrees
- Working current: 300mA max per colour
My question is what is the best way to increase the output (signal) of the 4017 to drive these LEDs? Please don't immediately flame me for not putting up a schematic. I am not asking for the specifics of the circuit I need - just the best approach. Should I be thinking mosfets, transistors, optocouplers, transformers or something totally different?
Cheers
