LM5122: FET selection

Part Number: LM5122
Other Parts Discussed in Thread: CSD17309Q3, CSD18543Q3A

Hi team,

I am doing LM5122 simulation using WEBENCH. The WEBENCH link is here:

I’d like to ask your help about FETs.

Webench chose CSD17309Q3 for M1 and CSD17575 for M2, but we are considering change M1, M2 FETs to CSD18543Q3A.

Because It is same package and Vds 60V. and our system need operation in wide-input voltage.

Is it possible? If not, please recommend FETs.

our system requirement is below:

- Input Voltage range :8~60V

- Normal Operation voltage : 9~28V

- Vout : 22V

- Iout : ~10A
