Do you understand that there's a difference between current limiting and constant current?

The module appears to have current limiting. That doesn't mean current will constant at any limit you set.

No i dont really know the difference ?
What does you mean?

And why u think it is current limit not constant current ?

For constant current, the current would be constant.

For current limiting the maximum current will be limited, but it can fall below that level. Google hiccup current limiting.
So i think current limit will be what i'm looking for.
How this module achive current limit for lm2596 ? Does it rely on variable resistor ?
