Part Number:TPS548A20
Hi expert,
My customer want to use TPS548a20 for their 12Vin->0.95Vout/13.05A, OCP=15.3A application. They use 1uH inductor and 3*47uF+2*22uF+2*220uF output cap. They are wondering why datasheet has below limitation on RTRIP but WEBENCH result would be 68.1kohm. And also I use equation to calculate IL_peak, it should be 21.54A if we use 68.1kohm as RTRIP. Could you kindly tell us why datasheet has this limitation and how to calculate RTRIP if we want to set OCP at 15.3A? Thanks a lot!!
Best regards,
Ann Lien
