[z_mx]

hi everyone
first of all i want to say thanks for the replies
my problem is: i have unstable load resistor (range from 1 to 7 Omh) in next circuit:

i need, that drain current will be constant 4A. what kind of feedback i will must put to the gate from Rload?
thanx

Hi
Although i think i've saw another thread just like this from you but your answer is using a simple hiccup current limiter .
