1.2.1 Input and Output Capacitors

Footprints for an additional input capacitor (C11) and output capacitors (C9 and C10) 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 TPS62851x 2.7-V to 6-V Adjustable-Frequency Step-Down Converter in SOT583 Package Data Sheet.
