I would like to know to to calculate the Rfset depicted in Figure 41 of TPS54240 datasheet (in page 20).
Is Rfset = RT (in kOhm) as defined in equation of 11 (in page 22) ? I cannot find any other equation that define Rfset.
If my external sync clock is around 450kHz, what's the proper Rfset I should use?
Yes, EQ 11 is the correct equation. For 450 kHz, I calculate 267 kohm.
