Part Number: TPS543B20

Hi,

Could you tell me the notes of the connection guideline and layout guideline of the RSP/RSN pin.
Also please give me the material related to it.
Customers use remote sense (differential) DCDC for the first time.
Therefore, I would like to introduce the you have materials.

Best Regards,

Yusuke,

There are layout guidelines with notes in the datasheet. Are you looking for something different? Please let me know.

John-san,

Thank you for your response.
The following contents are described in the datasheet

about RSP and RSN pin.pdf

However, there is little information on noise countermeasure and recommended layout position.
Do you have white note and layout material on remote sense prepared by TI?

Yusuke,

We do not have anything specific on that topic. I put together a slide showing routing based on the EVM design. Let me know if you have further questions.Example of RSP and RSN Routing using EVM.pptx
