Hi Shifali,

I updated the calculator to 12Vin, I think the schematic text of 5Vin is incorrect. Please confirm.

The current compensation selection of COMP #10 is predicted to only have about 40deg of phase margin. I would recommend changing to COMP #9.

Everything else looks good to me. I attached the updated spreadsheet for your reference.

Thanks,

Joseph

Hi Joseph,

The input voltage is 12V and no 5V. Thanks for the feedback.
