Hello all,
Im trying to build a circuit which can drive a single led at 2amps,as of now im using 3 mosfets connected in parallel to share heat,would be glad if any experienced people can guide me to build a circuit of above mentioned requirements.



with this post i have attached the circuit diagram of driver only taken from instructables.com FTFKKU6Z2HEWIFNTP5_002.jpg
 

i have built the circuit of above mentioned requirement...will be posting it soon after complete testing
 

2 amp for the LEDs will be really scary for me.....you really need the power LED for that.....In my view you need to choose right LED first...... Normal LED can work max up to 100mili-amp so be careful... and second important point is what is the level of voltage i mean voltage level ....I think you can have low voltage like 3 volts but in that case you need to have an idea mosfet is voltage controlled switch So you need to choose the proper voltage triggering mechanism for it ....I mean bootstrap or some thing like that ....

The last point is better you use simple NPN transistor like SL100 with bias method to archive the objective that you said....

Good Luck
