Hello,

In TPS51124, TPS51125A, TPS51218, could we simulate the function of over current protection corresponding each value of Rtrip?

Hello Thu,

Yes, you can simulate the over-current detection thresholds based on the Rtrip for all the models in question. Please use the equation as per datasheet to determine how much is the maximum inductor current based on Rdson of low side MOSFET and Vtrip.

Thanks
