Q1: Why Rs2 is not present in below formula? I think Ivsl(run) go both RS1 and Rs2, isn't it ?
Q2, I am doing the design from DC input and the VIN(min) is as low as to 50V,output is 12V/1A @CV mode; but from the simulation result, the VOUT and VS is rise up to about 1V and then down to zero, I am checking if VIN fault is detected, I see there is a 4us detect as below showing from datasheet. I don't understand this principle, "If the CS is input is short or held low" means the MOSFET is on ? can you explain this 4us detect how it works?
