1.3.2 Input and Output Capacitors

C2 is provided for an additional input capacitor. This capacitor is not required for proper operation but can be used to reduce the input voltage ripple.

C7 is provided for an input capacitor on the AVIN pin. This capacitor is required and populated on the TPS62130EVM-505. It may be added on the other EVM versions but is not required.

C4 is provided for an additional output capacitor. This capacitor is not required for proper operation but can be used to reduce the output voltage ripple and to improve the load transient response. The total output capacitance must remain within the recommended range in the data sheet for proper operation.
