Hi Experts,

Good day. Seeking help for UCC28740 application.

I am having one technical query regarding one SMPS Circuit which we are trying to implement. There is M2 mosfet, which we plan to place on Return path of the circuit . Can we put it on the top of the path like I have attached on second picture.

See attachments from Webench.

Any advise?

Thank you!
