TPS23753 abnormal in high temperature conidition

Other Parts Discussed in Thread: TPS23753

My customer use the TPS23753 in IP Camera application. When they do the high temperature testing, they find some output of the secondary is abnormal, the output is only 3V(Typical is 5V).

They cold down the ambient temperature, the output still maintain 3V.

The output can only be recovered by shut down the input after several senconds.

Do you have any suggestion for this issue?

How about the detail explain about the OCP function with TPS23753? I can't find it in our datasheet.
