I'm making my first voltage regulation first with a buck converter, but I'm having some trouble making sense of the following datasheet. https://www.ti.com/lit/ds/symlink/tps560200.pdf
So I've made the circuit with the recommended components values given in Table 2 in section 188.8.131.52. Now I expect the table to give me the right results, but I did also gave equation 2 a try to calculate the
I want an output of 3.3V, and I use the 20kΩ as recommended in the table for
R1. This makes me end up with
R2 needing a resistance of 6400Ω (=20000*0.8/(3.3-0.8)), but if I compare that with the 61.9kΩ recommended, then I get really confused as to how they arrived at those values, as those two values are nowhere near each other. Also, the equation of
R2 seems to be inverted proportional to the values recommended in the table.
I would really appreciate an answer on what I'm doing wrong, as I, by default, assume I am as it's my first switching voltage regulation design.
