LMR23610: LMR23610 Input current instability

Part Number: LMR23610

Hello,

We our using the LMR23610 in a product that has been in production approximately one year without any issues with this part. Recently we have had six units with erratic current draw during production testing. I have traced the source back to the LMR23610. Replacing the chip with another one seems to work to fix the problem however I would like to know if there is could be some underlying design issue that could result in this instability. Is there a way to have someone from TI review our implementation of the LMR23610?
