Hi Team,
We're using the LMZ34002 in a new design with a PI filter (ferrite bead) on the output for noise reduction.
Can we connect VOUT to A_VOUT after the ferrite bead, or should it be before the ferrite bead?
Any compensation concerns one way or the other?
Thanks,
Joe
Hi Joe,
Referring to section 12.18 of the datasheet, you should connect VOUT and A_VOUT.
Just keep in mind that you need to dedicate some layout area to Vias underneath the IC for good thermal performance.
It is used as the internal reference voltage so, there could be some compensation issues if you connect it the after the bead as you mentioned.
Thanks,
Andrew
