TPS62291: TPS62291 Voltage rating

Part Number: TPS62291

Hi TI,

My customer found damages in the test of using TPS62291.

The output of TPS62291 is disconnected from system using P-ch FET(like a load switch) in standby mode because of Iq.

At the same time, The output of LDO is connected to system. 

They are controlled using MCU and simultaneously turn on for 500usec because of turn on time.

I request schematic review whether there is some problem.
