6 FAQs about [Single group capacitor capacity selection]

How to select an output capacitor?

・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.

How to choose a multilayer ceramic capacitor?

How to choose a capacitor?

Based on the input voltage, the input current RMS current, and the input voltage peak-to-peak ripple you can choose the capacitor looking at the capacitor datasheets. It is recommended to use a combination of Aluminum Electrolytic (AlEl) and ceramic capacitors.

How to select bulk input capacitors?

There are two key factors for selecting bulk input capaci-tors: 1) overshoot and undershoot requirement of transient response; and 2) allowable ripple current requirement. The ESR of the bulk capacitor (ESRB) and the capaci-tance (CB) need to meet the transient response requirement.

What parameters should be included in the selection of output capacitors?

The most important parameters are the magnitude of the load transient (ΔI) and the distributed bus impedance to the load. The selection of the output capacitors is determined by the allowable peak voltage deviation (ΔV). This limit should reflect the actual requirements, and should not be specified lower than needed.

What factors should be considered when selecting a capacitor?

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.
