TPS53511: how to improve Vout voltage ripple of TPS53511

Part Number: TPS53511

Hi team,

As you know, our TPS53511 has the skip mode for light load condition. So the Vout ripple is larger than the other solutions.Do you have the suggestion how to improve it with the device? i can only find to increase the L value. Thanks.

    There are not many adjustments that can be made other than the external component values and the switching frequency. 

    Increasing the output capacitance can reduce the ripple.    How much ripple and Do you have a schematic and oscilloscope plots?
