OCP in DC-DC converter ?

[Btrend]

hi all,
I had a question about the OCP (Over Current Protection) in DC-DC converter.
Whether or not the OCP should be enabled during soft-start period of a buck converter?
consider the following cases in a buck converter
1. Output short circuit, and u still want to soft-start the output, u will encounter large current in this period, such that the high side switch maybe overheat. ??
2. Output is in light/heavy load conditions, then u still get an in-rush current which maybe large enough to trigger ur OCP , or "probably" burn down ur switch ??

thanks in advance

It typically should be enabled during soft-start. The purpose of OCP is to protect the load and the power supply from damage.
