8.2.2.4.1 CCP Capacitor

The capacitance of CCP determines the maximum output current of TPS63710. Therefore it is selected at first. A minimum 4-uF of effective capacitance is required to support the full output current of 1 A. Only ceramic capacitors like X7R, X5R or equivalent are recommended. For applications that require a lower maximum output current, its value can be reduced linearly. As the voltage at the CCP capacitor is equal to the input voltage VIN, the dc bias effect has to be taken into account based on the maximum input voltage. Table 6 shows recommended CCP capacitors.
