TPS25921A: Tolerance of ILIM in Design Calculation

Part Number: TPS25921A
Other Parts Discussed in Thread: TPS25921EVM-637, TPS2596

Dear all

I would like to ask a question about Design calculator.

The values of the following items (red frame) of "TPS25921EVM-637 Design Calculator Tool" are as follows.
① The items in the red frame are calculated from the tolerance of RLIM, but if you check the Excel formula, the square root of the sum of the square of the tolerance of RLIM and the square of 0.08 is calculated. . What factor does 0.08 (8%) mean here?

(2) Check the min, typ, and max values of ILIM in the data sheet, and the min and max values are specified at about ± 20% of the typ value. On the other hand, the tolerance of the above red frame is 8.1%. Which value is the correct current limit error?

Best Regards,
