8.2.1.2.5 Output Capacitor Selection
Output capacitors must be selected to meet the required output ripple and transient specifications.
Equation 45.
Equation 46.
A Panasonic EEEFC1V330P 35-V 33-μF, 120-m? bulk capacitor and a 6.8-μF ceramic capacitor are selected to provide the required capacitance and ESR at the switching frequency. The combined capacitance of 39.8 μF and ESR of 60 m? are used in compensation calculations.
