Calculating Output Ripple voltage from Output Ripple Current

Thread Starter

Hi All,

I have this Buck converter. TPS54260. Stepping 16.5V max to 5V DC Output.

I have an 220uF 16V output Cap having ESR of 0.16ohms.

In the datasheet of TPS54260, how can I calculate the output voltage?

Only output ripple current formula is given.
My idea is, I will calculate the output ripple current from the formula and multiply this output ripple current with the ESR of the output cap which will give me the required output ripple voltage. Is my approach correct? Please help.

And in the datasheet, I would also like to find the tolerance of the output voltage. How to find them? Can you please help.
