Hello,

Please review the TPS544B20 schematic using the datasheet as a reference. R680 and R676 should be 48.7ohms.

Would recommend a Series RC from comp pin to GND as a Do not stuff also. I would also recommend a placeholder for a 47pF cap across R681.

Regards,

Mathew

Dear Mathew.

Thank you very much for the review comments.

Please let me know, If we are not using PMBus telemetry in our design, VOUTS+ and VOUTS- connection can be retained as shown in our schematics?

Also let me know on the TPS54526PWP review comments.

Thank you once again
