to the operation the Troubles with-by approach help pinpoint the get again or airflow if necessary. PCB Integrity: Use a multimeter to check for shorts on the PCB. If found, fix the issues immediately. Inductor Check: Verify that the inductor is of the correct value and in good condition. Feedback Verification: Ensure the feedback loop components are correct to maintain proper output voltage.

By following these steps, you can diagnose and fix common issues that prevent the LMR23630ADDAR from starting up. Make sure to refer to the datasheet for exact component values and layout recommendations.
