Hi Teja,

Overall looks fine. Just one comment UVLO rising can go upto 1.25V. In that case UVVIN can go upto 49V which is above application voltage of 48V. We need to adjust bottom resistor to decrease UVVIN below 48V.

Hi Kunal Goel,

Thanks for your valuable Feedback. Regarding the UVLO rising as 1.25V we had updated the resistors corresponding to the UVLO pin for 47V.

Please find the updated schematic image below and share your feedback on that.

Thanks and regards,

Hi Kunal Goel,

Could you please confirm what is the use case of giving this VIN supply at NC pins in the EVM reference of TPS16530RGE as shown in the figure. could you please confirm if we also need to provide a connection like that?

Hi Nimesh,

It is not necessary.
