AMC7135 is very famous in led driver and some people use it with 12v supply. the voltage drop is very small compare to LM317.
what is the other advantage from AMC7135?
the heat dissipation is also low?
if the voltage supply is 12v and running 3v 1A led,
1. zener drop 12v to 5v or 6v than constant current using LM317
2. zener drop 12v to 5v than constant current using AMC7135
which one is better? what is the advantage and disadvantage?
