5.2.2.3 Output Capacitor Selection

The hysteretic PWM control scheme of the TPS65216 switching converters allows the use of tiny ceramic capacitors. Ceramic capacitors with low ESR values have the lowest output voltage ripple and are recommended. The output capacitor requires either an X7R or X5R dielectric.

At light load currents the converter operates in power save mode, and the output voltage ripple is dependent on the output capacitor value and the PFM peak inductor current. Higher output capacitor values minimize the voltage ripple in PFM Mode and tighten DC output accuracy in PFM mode.

The buck-boost converter requires additional output capacitance to help maintain converter stability during high load conditions. At least 40 µF of output capacitance is recommended and an additional 100-nF capacitor can be added to further filter output ripple at higher frequencies.

Table 5-2 lists the recommended capacitors.
