TPS2546: TPS2546 output current issue

Part Number: TPS2546

Hi ,

There is TPS2546 issue in customer, which is PC application.

They use TPS2546 in Type A port for power limition.

 

Please see follow schematic, the current limit is 0.95A that R267 is 30.9K,  when they decrease the value of R267, the current limit will be increase.If R267 is 12K, , the current limit is 1.7A. it is wrong current limit value according Ilim resistor, they borrow the circuit from another project, but in another project, no the same issue.

 

Could you please give some advice for the issue? Thanks!
