This applies to the TPS2474x Design-in Calculation Tool Rev B available on the ti.com as of today.
In the Reverse Current Threshold section... (Step 7)
When calculating the min rdson in cell F115, the formula is "F113/F114" This works if the rdson is 1 mohm as is shown in the default example (1mohm typical, 1.15mOhm max yields 0.87mohm min)
The formula does not work if the rdson selected is, say, 14mohm typical & 17 mOhm max - the formula would calculate 14/17 = 0.82mOhm for rdson min which is wrong and causes errors in other calculations.
A better formula would be "F113/F114 * F113" for instance.
Please verify and correct the equation as needed & update the spreadsheet on ti.com
