Hi Delmore,
Please note below main differences.
1. TPS51397A is a 10A part, while TPS51396A is a 8A part. So 397A has larger over-current limit (12A) than 396A (9.8A).
2. 397A output range is 0.6~5.5V, while 397A output range is 0.6~7V.
3. The Mode-pin settings of two parts are different.
4. The recommended L/Co/Cff values are not completely same, please refer to datasheet for details.
You can send us the schematic for final review.
