Hi,
I have used the LTM4644IY#PBF part in my design previously for 12V to 0.84V conversion, since it does not have any remote sensing pin I have changed from the LTM regulator to TPSM843B22.
Kindly review the attached power section pdf which we designed for 12V to 0.84V.
Let me know your comments as soon as possible.
