I'm trying to get some 3W RGB LED's (6 pins and 350mA/channel) to work. The powersupply is 5V. I could change to 12V if necessary.
The setup initially is to work with a TLC5940 and a mosfet. And trying to make my life a little easier if possible also to connect the same mosfet directly to the arduino. (For future lighting idea's :))
I red a lot of topics concerning the TLC5940 and/or mosfet. So much that I'm actually totally lost.
If I understand correct with a TLC5940 it is possible to generate a constant current through a mosfet? So that there is no need to have resistors in the led circuit.
My second questions is which mosfet can do the job? I was thinking about a 500mA mosfet. And is it possible to use the same mosfet directly connected to the arduino? I guess I need to add a current limiting resistor.
Just as mention, I got 3 IRLD024 mosfet's lying around.
