1.2.1 Input and Output Capacitors

Footprints for an additional output capacitors (C15 to C20) are provided. These capacitors are not required for proper operation but can be used to reduce 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 TPS6244x-Q1 2.75-V to 6-V Dual Step-Down Converter with Adjustable Frequency in a QFN Package data sheet.
