1.2.1 Input and Output Capacitors

C6, C7, and C8 are provided for additional input capacitors. These capacitors are not required for proper operation but can be used to reduce the input voltage ripple.

C9, C10, C11, and C12 are provided for additional bulk output capacitors. These capacitors are not required for proper operation but can be used to reduce the output voltage ripple. The total output capacitance must remain within the recommended range in the TPS62903-Q1, 3-V to 18-V, Low IQ Buck Converter in 2.2-mm × 2-mm VQFN with Wettable Flank Package data sheet for proper operation.
