The explanation of Milo is still not clear to me.

What is the difference if TPS2560/1 and TPS2560/1A.

The Ios is specified different. On the other hand the caluclation formula is the same.

Hi, Martin,

It's a historical reason. There were some customer asked us guarantee 2.1A to 2.5A current limit including external +/1% resistor in production, which can't be met by TPS2560/1, so we release TPS2560/1A to ensure the current limit from 2.1A to 2.5A and state it in datasheet as below.

So the calculation formula is same, but the monitor point is different.

Regards,

Bob
