8.2.1.2.4 Output Capacitance
The necessary output capacitance of the secondary side can be found using Equation 11.
Equation 11. 
where:
- DMAX is the maximum duty cycle, which occurs at the minimum input voltage
Assuming that an output ripple of 15 mV is specified, states that a 60.60 μF output capacitance must be selected. Accounting for capacitance equivalent series resistance (ESR) ripple, a 100 μF capacitor is selected.
