For the TPSM82480, the customer is copying the layout example in the datasheet, figure 39. They would like to make the footprint smaller by moving the output caps closer together and moving the feedback resistors and softstart cap to the other side of the board.
Move C3/C4 and C7/C8 closer together so the ground pad placement is where the feedback resistors were. In addition move R1, R2,R3 and C5 to the bottom side of the board.
Do you see any issues with this?
If need be I can send you the layout, please send me an email.
