TPS22965-Q1: Backflow issue

Part Number: TPS22965-Q1

Hi team

My customer has a backflow issue with TPS22965Q1, here I describe the issue:

The following picture is customer's schematic design:

Issue description:

1. When there is no VIN, if FB pin has voltage, it will flow from VOUT to VIN; 

2. When there is no VIN, if we remove the FB15, there is about 0.34V voltage comes from ON to VIN. Could you please help to double check with customer schematic design? Thank you.
