LT8390

Expected Functionality:
We expect to be able to apply up to 60V DC input and regulate out to +12V using the LT8390

Issue:
When voltages > 17.5V are applied to the input (+VBATT), the output of the LT8390 begins to oscillate. At input voltages < 17.5V the output is regulated as expected.

Please review schematic/bom and help us locate the issue.
