Dear TI Support,
Hello, I am currently using the LAUNCHXL-F28379D and would like to power the control board using an external 5V source. Following the instructions in the user manual, I have removed JP2, JP3, and JP6, and supplied 5V through the J16 header.
However, during testing, I measured only 2.7V on the 3.3V power rail of the board. Is this behavior expected?
Should the 5V input be automatically converted to a stable 3.3V by the onboard regulator?
Thank you for your assistance.
Best regards,
Andy Chen
