ZHCSJW0D June 2019 – March 2020 TPS62840
The DCS-Control scheme of the TPS62840 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. Larger output capacitors reduce the output voltage ripple. The leakage current of the output capacitor adds to the overall quiescent current.
