Part Number:TPS53355
Hello Team,
I'm looking for some further insight into how the ripple generation values should be chosen based on the design example in the datasheet. These calculations don't match another app note we have on the subject SVLA653. In the datasheet section 8.2.1.2.2, the C2 value is set to 1nF first (how was this value chosen?), and then C1 is set in a range of 10 to 100xC2 based on equation 11. In the app note on page 5 C1 is set first, and then C2 is set to be 3 or 4xC1 (the opposite relationship).
I'm trying to understand which equation set is correct and why the design example for TPS53355 would have the opposite relationship for the component selection.
