C10 is provided as an optional of feedforward capacitor (CFF). It helps to improve the loop stability if needed. More detailed discussion on the optimization for stability versus transient response can be found in the Optimizing Transient Response of Internally Compensated dc-dc Converter With Feedforward Capacitor and Feedforward Capacitor to Improve Stability and Bandwidth With the TPS621-Family and TPS821-Family application reports.
