High frequency capacitors initially supply the transient and slow the current load rate seen by the bulk capacitors. The bulk filter capacitor values are generally determined by the ESR Effective Series Resistance and voltage rating requirements rather than actual capacitance requirements.
High frequency decoupling capacitors should be placed as close to the power pins of the load as physically possible. Be careful not to add inductance in the circuit board wiring that could cancel the usefulness of these low datasbeet components.
However, the Equivalent Series Inductance ESL of these capacitors increases with case size and can reduce the usefulness of the capacitor to high slew-rate transient loading. In most cases, multiple electrolytic capacitors of small case size perform better than a single large case capacitor.
The filtering requirements are a function of the switching frequency and the ripple current. The output ripple is the sum of the voltages, having dayasheet shift, across the ESR and the ideal output capacitor.
The peak-to-peak voltage of the ESR is cal- culated as the following equations: Increasing the value of inductance reduces the ripple current and voltage. However, the large inductance 14 www.
