TPS53014: TPS53014 question about Is it damage the IC when the input / output voltage reverses?

Part Number: TPS53014

Dear supportmember

My customer used TPS53014.

I have a question.

(Situation)
First
TPS53014 turns the output low by setting EN low.

Second
The input voltage is lowered.

When input voltage is lowered,the voltage of the output of TPS53014 remains.
The input / output voltage reverses by about 600 mV max.


(Question)
There was a situation to reverses by about 600 mV,
Is there any possibility that this will damage the IC?


Best regard.
Bob Lee.
