question on buck over current protection

[totoro]

If my over protection circuit sense the current of PMOS is larger than the limitation and turn off the PMOS, when should it turn on again?
Next clock cyle? or until the voltage LX is fall to zero?

At current mode --> Next clock cycle

At voltage mode --> away over-current protection, and then set

Thanks for your reply！
what do u mean by "then set"?

 

[edwintsu]

At voltage mode, ocp is a fault protection. If ur ocp is recovered, the logic is back to normal situation.
So the "then set" is normal situation. ^_^
