Tool/software:

Hello TI team,

We are using some TI ICs in power section of our design. The Designator and its part numbers are as below,

1. U24: REF35300QDBVR

As we have completed the layout we would like to review it from TI team. I am attaching the schematic sheets PDF containing the IC listed above. I am also attaching the Gerber document for review.

Please review attached files and let us know if any changes are required.

Regards,

Nitesh

Hi Nitesh,

I see no issue with the schematic and layout. Out of curiosity, What is the 1.678V used for? We have 1.7V output option for REF35: REF35170QDBVR, would this be close enough for your application? Maybe it could save you some space or components by eliminating the need for the voltage divider.

Thanks,

Hello Jackson,

Thanks for the layout review and response. We are using 1.678V as a reference voltage in signal conditioning circuit. Thanks for suggesting 1.7V output option, we will think about it.
