Hi TI Team,

We have uploaded our Charger Specification Sheet along with the TI Design Inputs and Calculation Sheet, prepared based on our charger requirements.

We kindly request you to review the shared documents and provide your feedback or suggestions to help validate our design.
Additionally, we have a few queries regarding the controller IC (UCC256403DDBR) design, which we will share shortly.

Hi Prajal,

Thank you for your patience. Please see the below comments.

In the excel sheet, please select RISNS value at least 20% lesser than the recommended value.
I hope you have selected option 6 ( BMTL/BMTH=0.6) for BW as per your requirement.
