## How Does the Capacitance of the Output Capacitor Affect the Peak-to-Peak Ripple Voltage?

The capacitance of the output capacitor in a buck converter circuit significantly impacts the peak-to-peak ripple voltage. Higher capacitance values result in lower ripple voltage, as the capacitor can store more charge, smoothing out voltage variations. Conversely, lower capacitance values lead to higher ripple voltage due to reduced charge storage capacity. Therefore, selecting the appropriate capacitance is crucial for meeting voltage ripple specifications and ensuring stable circuit operation.
