Hi Sri,

While I review your schematic, would you mind clarifying what you mean by internal doesn't power on?

Regards,

Conner

Schematic Checklist Rev 2p0.xlsx

Please review the attached schematic checklist (Tab TPS25730D). The reason for the issue you're seeing is that the FAULT_IN/ pin isn't setup correctly. For this pin, connect to LDO_3V3 through resistor.

Can you please clarify the behavior you're seeing? Are you able to capture any plots of VBUS and LDO_3V3?
