TPS63060: Vout max margin

Hello,

I think TPS63060 Vout max of 8V is defined by the internal OVP.

Is it a possible idea to know the OVP value even not described on the datasheet?

My customer uses it with Vout=8V and wants to know if it is marginal enough with expected variation including accuracy and ripple?

Thanks in advance.
