I need clarify the equation to calculate output capacitor on flyback converter.
I am looking for the equation of output capacitor on the data sheet of two LTC products, LT8300 and LT8302.
The equation of COUT is same in both of LT8300 and LT8302 as blow.
However, LT8300 uses the ISW value as actual value in the example use case (P.17) but LT8302 uses the maximum value (p.19). Which value of actual and maximum should I use?
You should use the actual value.
In both examples, the actual value and maximum value are very close, at full load and minimum Vin.
