Inspect solder joints and connections.
Test the Load: Confirm that the load is within the 3A rating of the TPS54320RHLR . Any excessive load current can cause issues with voltage regulation. PCB Layout Review: Double-check the layout, especially the ground plane, feedback path, and power traces. Replace the IC: If all other solutions fail, the TPS54320RHLR itself may be damaged. Replace the IC and test again.By following this structured approach, you can quickly identify and resolve common voltage regulation issues with the TPS54320RHLR, ensuring stable and reliable power for your system.
