    Hi Tat,

    I reviewed the schematic and I do not see anything that would cause a problem. I assume the components marked NU are not loaded. Please verify that R15 is not loaded.

    Also, it would be helpful to see your layout. You could send it to me directly at jarrigo@ti.com It would be helpful to send PDFs of each layer and include the area around the device.

    Thanks, Jason
