When creating design for TPS40303 for Vin=3.3V, Vout=1.00V/20A
1)I am not able to choose other M2 (lower FET), but only M1.Why?
2)Why when choosing ME FET from TI, I can not get any M2 FET from TO too?
3)I choose M1 as CSD16325Q5 and got Efficiency of 94% ,but when I run this simulation with the SwitcherPro, and would like also to choose CSD16325 for appear FET, I got below massage:
This MOSFET caused the basic design calculations to fail!
High-side MOSFET Rdson calculation failed.
This device doesn't have a good rdson specifications.
