It depends on your application. The maximum recommended current limit is 14 A. You need to know Vin, Vout, Fsw and Lout to solve for the maximum Rtrip value using equations 4 and 5 in the datasheet.

John-san,

Thank you for your support.
When using the simulation tool (webench),
I could not simulation only up to 10.1A.
For that reason,Customer had a question.

Best regards,

That may be a webench issue. I suggest you post in the power an lighting tools forum.
