TPS53622: one question about the power on sequence of TPS53622A

Hi,

We recommend below power one sequence for TPS53622A in the datasheet:

3.3V->5V->PS_EN->12V->VR_EN;

but for the input rails limitation, customer is hard to achieve it. Customer wants to confirm is there any risk for below sequence.

12V->3.3V->5V(PS_EN pull to 5V)->VR_EN(make sure VR_EN is last enabled).

Can you give a comment?

Thanks a lot.
