Hi,
When running a webench design, webench came up with the wrong output Voltage setting ratio for Rfb1, Rfb2. As this these resistors are also part of the ripple reduction network, I would prefer to use the optimized webench values as opposed to simply using the data sheet formula Rfb2/Rfb1 = (Vout/1.25) - 1
Webench specified 805 ohms and 10K, clearly the wrong ratio for a 12 Volt output.
