1.2.3 Feedforward Capacitor

C5 is the feedforward capacitor. If the feedback divider (R1 and R2) has been modified it may be required to adjust the value of the feedforward capacitor as well. For recommended values, see the TPS6281x-Q1 Low Input Voltage, Adjustable-Frequency Step-Down Converter data sheet.
