I’m looking at the Over-Current Protection section of the datasheet, and it gives both a formula for computing Rcs and a table of Rcs values for typical applications (Table 2). However, plugging in the numbers from the table into the formula doesn’t give the same results that are listed in the table. For example, if I use the values in the third row of the table (Vin=12V, Vout=1.8V, Rcs=16.2k, Fs=1MHz), I end up with a current limit of 10.8A instead of 10. Using the formula, I find I’d need Rcs=20.9k (round to 21k if we’re using standard 1% values) in order to get a current limit of 10A, instead of the 16.2k that the table suggests.

My guess is that there’s either an error in one of the given parameters (e.g. Vocp, Gcs) or the values in the table were computed incorrectly. I’d appreciate it if anyone can shed some light on this.
