The output capacitor is selected to minimize the capacitive ripple across it. The maximum ripple is observed at maximum input voltage and is given by Equation 12.
Assuming VIN = 95 V and substituting ΔVripple = 10 mV gives COUT = 2.6 μF. A 4.7-μF standard value is selected for COUT = C9. An X5R or X7R type capacitor with a voltage rating 16 V or higher must be selected.
