APPLICATION INFORMATION
design procedure
capacitor selection
The TPS6030x devices require only five external capacitors. Their values are closely linked to the required
output current and the output noise and ripple requirements. It is possible to only use 1-
F capacitors of the
same type.
The input capacitor improves system efficiency by reducing the input impedance and stabilizing the input
current.
The minimum required capacitance of the output capacitor (CO) that can be selected is 1 F. Depending on the
maximum allowed output ripple voltage, larger values can be chosen. Table 1 shows capacitor values
recommended for low output voltage ripple operation. A recommendation is given for the smallest size.

Table 3 lists the manufacturers of recommended capacitors. However, ceramic capacitors will provide the
lowest output voltage ripple due to their typically lower ESR.
