Part Number: TPS54561
Other Parts Discussed in Thread: TPS54361

Please find the attached excel sheet , which is downloaded from TI website.When I put the output current more than 4A, that column color changes.

May I know the reason for the same?

Thanks,

If I select TPS54361 (cell B3) and set the output current (cell B14) for 4.5 A the cell B14 turns red. If I select TPS54561 and set the output for 4.5 A cell B14 remains yellow. So I think this is OK. Let me know if you are observing something different.

Please read John's reply. On the first row of your picture, please select TPS54561, not 54361. TPS54361 only support up to 3.5A, that's why the cell color turns red. 54561 supports up to 5A.
