Part Number: TPS53659

Hello,

I have a question about TPS53658 layout.

Is there any guideline of how to place Sense resistor of this controller? should put it near controller or other side or middle, which one is better and what's the difference?

Looking forward to your reply.

Thank you.

Hi Penn,
Do you mean input current sense resistor? It is no need to put resistor near controller, you can leave it near the load, and to use differential pair to route CSN_IN/CSP_IN.

Thanks.
