We may infer from Figure 2 that the DC link capacitor''s AC ripple current Icap arises from two main contributors: (1) the incoming current from the energy source and (2) the current drawn by the inverter. Capacitors cannot pass DC current; thus, DC current only flows from the source to the inverter, bypassing the capacitor. Power factor
For most TPS6220x applications, the inductor value ranges from 4.7 μH to 10 μH. Its value is chosen based on the desired ripple current. Usually, it is recommended to operate the circuit with a ripple current of less than 20% of the average inductor current. Higher VIN or VOUT also increases the ripple current as shown in Equation 1.

Use output capacitor(s) with lower impedance at the switching frequency. This will be the focus of the discussion here. Paralleling output capacitors is an effective way to achieve this. Here is an example of LF ripple reduction by using two parallel capacitors instead of one: Also, you can choose a different capacitor type altogether. Here is

The change in current that flows through the DC capacitor will yield the change in charge (Δ q). An increased switching frequency will narrow the width of each DC link capacitor''s current pulse. This narrowing decreased the stored charge variation of the capacitor. In other words, the capacitor charge variation is proportional to the PWM switching frequency. For this reason, the

In succession to selection of inductors, we turn to a discussion of capacitor selection. Capacitors that are essential for a step-down DC-DC converter include output capacitors and input capacitors. We begin by explaining output capacitors. Similarly to inductor selection, the choice of capacitor is also very important.
・When selecting an output capacitor, the rated voltage, rated ripple current, and ESR are important parameters. ・In addition to smoothing and regulation, output capacitors are also closely related to the output ripple voltage. In succession to selection of inductors, we turn to a discussion of capacitor selection.
Smaller capacitors are acceptable for light loads, or in applications where ripple is not a concern. The control-loop architecture developed by Texas Instruments allows the designer to choose the output capacitors and externally compensate the control loop for optimum transient response and loop stability.
The following three factors are important when selecting the output capacitor. Of course the voltage and ripple current applied to a capacitor must be below the maximum ratings for the capacitor. The ESR is an important parameter that determines the output ripple voltage associated with the inductor current, and must be studied carefully.
