Hi Sir
I use TPS40304 to run Vin 12V and Vout 1.2A/Iout 25A.
initial run out high side MOS(M1) is CSD16340Q3 and Rs is 3.32Kohm.
and i change high side MOS to CSD16323Q3, the Rs is still 3.32Kohm.
I use DataSheet 7.3.5, the calculate Rs should be around 8K. May we know which is correct?
as below are some parameter that i use. the Rs is for adj OCP. so i am want sure what is correct.
CSD16323Q3 = 4.4mOhm (Vgs=4.5V)
Ip-p = 25A * 0.3 = 7.5A
