Dear Support Team,
my company has succesfully used the TPS54560B IC in the design attached for a 12V to 5V conversion.
Due to recent shortages we had to choose an alternative part. We have the TPS54560-Q1 which seems to be compatible.
From what we've seen testing the two parts on webench, there should be no big differences in the converter's surrounding circuitry.
We tried a one to one substitution on our board, but it did not work. The system using the TPS54560-Q1 becomes unstable when the load current increases, and when it reaches values above 2.5A, Vout falls up to 4V or less.
Can you please suggest any solution for the new part to perform correctly?
