Hi,

Could you please review the attached schematics designed using LMZ22010TZ/NOPB.

Hello,

Overall the schematics look good.

What are L13 and L14, ferrite beads? And what are those used for?
Ferrite beads at the output can potentially degrade the load transient performance.

Also the R537 better be of 1 KOhms value. Can you use lower values for the feedback resistors of the 3.3V schematic?

Hi,

L13 and L14 are ferrite beads.

R535 and R537 are updated with smaller value resistors. It is shown below. Please go through it.

Hi Nikhitha,

The schematic looks good.
Except my previous comment about adding ferrite beads at the output.

Please when available send the layout for review as well.

Regards,

Yitzhak
