What sort of current limit do you want? you can cut out completely or foldback. For foldback just look it up, there is lots online about it. For cutout you would need a comparator and a latch I think, not something i have done before myself.

I want foldback current limiting
Simon:
Foldback is easy with SMPS, just measure the current and if you trip a threshold blank the gate drive to the switching element.

I don't understand  what you mean by blank the gate drive.
