TPS922053: Regarding Rcomp & Fzero calculation for particular application

Part Number: TPS922053
Other Parts Discussed in Thread: TPS922052

Hello Steven,

We are working on design related to TPS922053. There is mention of calculating Rcomp using fzero in link below. Now how do we calculate what fzero is required for any application? Please advise.

Hi Jagdish,

Sorry for the missing this thread.

For TPS922052/3/4/5, its structure is inherently stable, so normally no zero is needed here and R_COMP = 0ohm works.

Best Regards,

Steven
