So after some revisions and updates im having to change my plans again and I'm looking for the best way to power 6 RGBW LED. with (If max) of 4A (3A red so I'm aiming for 3A around) and an (Vf) of ~3.2v (red is about ~2.8v) and assume its being powered by a car.
Last thing, I also have MINIMAL space!
4ch
6x 4ch leds @3A/each ~2.8-3.2v
PWM dimming
I was wondering if I could have one power rail and use NexFETs to switch the ground on the leds with a resistor on the red to drop that .4v
The board will have SMT leds and SMT parts with taller TFT reverse mounted / SMT on rear
