1.2.1 Input and Output Capacitors

Footprints for an additional input capacitor (C22) as well as for additional output capacitors (C31, C32 and C33) are provided. These capacitors are not required for proper operation but can be used to reduce the input and output voltage ripple and to improve the load transient response. For proper operation the total output capacitance must remain within the recommended range described in the TPS6281x-Q1 Low Input Voltage, Adjustable-Frequency Step-Down Converter data sheet.
