Hi

in #7.3.6 Current Sense and Overcurrent Protection

it show "For the TPS53515 device, the overcurrent protection maximum is recommended up to 14 A only. "

but in webench @ power design, I only can set 12A.

what " Rtip vaule ""I can use , for 14A.

or TPS3514 itself have 14 OCP ?

    Dimitry,

    You may be confusing the output current with the current limit. The current limit threshold, which is determined by Rtrip, has a recommended range of 10.1 to 13.9 A. The output current, which is what is being set using Webench, has a range of 0 to 12 A.
