sir,
am working on a project of led lighting....
after doing some research work now m using led driver(CS8902) which would be giving constant output current of around 1Amp..the mosfet is used to switch on and off purpose(correct me if i am wrong anywhere)..
after calculation the total load current i require from each led driver is around 0.5 Amps..

now i am having some fundamental probs like
the attached pdf shows the n channel mosfet..how the specifications of the mosfet are to be decided????...

I have connected the LD pin of the IC to the I2c pin of microcontroller for giving the control signal or linear dimming input to the led driver ic..is it correct???..

i am using 4 different led drivers to drive 36 leds OF 1W EACH of red,green,blue,and white respectively(as arranged in the attached pdf)..so whether i need to use different control signals from micro to different led drivers(linear dimming input) or only 1 control signal would be sufficient from micro to all 4 led drivers..wat more m i missing.please suggest...
thanks in advance..

It would be better not to start multiple threads about the same subject.
