The DCS-Control scheme of the TPSM82830x allows the use of tiny ceramic capacitors. Ceramic capacitors with low ESR values have the lowest output voltage ripple and are recommended. To keep low resistance up to high frequencies and to get narrow capacitance variation with temperature, TI recommends using X7R or X5R dielectrics. At light load currents, the converter operates in Power Save Mode and the output voltage ripple is dependent on the output capacitor value. A larger output capacitors can be used reducing the output voltage ripple. Considering the DC-bias derating the capacitance, the recommended minimum effective output capacitance is 12 µF. The recommended typical output capacitor value is 2 × 10 µF or 1 × 22 µF with an X5R or X7R dielectric. Table 8-4
