TPS54260 Current limit threshold

In datasheet, current limit threshold is min 3.5A, typ 6.1A with Vin is 12V condition.

If Vin value changes, does the current limit threshold change?

If you have data, I would like to get it.

there is probably some variation. let me see if we have any data on it.

I have been busy on other urgent tasks. It will probably be next week.

It is not easy to find that type of data. I'll look again for it.

I checked again but could not find any data. I was able to find some information on a similar part. It looks like the current limit is fairly constant above 12 V, maybe less than 100mA increase in current limit as input voltage rises. At low Vin, The current limit may be about 300mA lower than typical.
