1.2.1 Input and Output Capacitors

C4 is provided for an additional input capacitor. This capacitor is not required for proper operation but can be used to reduce the input voltage ripple.

C10, C14, and C15 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 TPSM8291x 3-V to 17-V, 2-A/3-A Low Noise and Low Ripple Buck Power Module with Integrated Ferrite Bead Filter Compensation data sheet for proper operation. C11 and C16 are provided for high-frequency bypass capacitors.
