TPS543C20A: RSP RSN Differential

Part Number: TPS543C20A

Tool/software:

Hi Britton,

Final question before I release this design.

For the RS_P &RS_N lines, I provided pictures of the schematic/layout.

Does how I routed the input to the sense amplifier look correct? The data sheet mentioned differential routing/input. 

 L1 1.55V &GND vIAS TO L3

 L3 GND ties to RS_N

 Differential route RS_N &1.55V

 1.55v goes through top feedback resistor RS_P_RSN route differential to RS_N &RSP pins

Thank you,

Matt

  •  Hi Matt, Yes these differential traces look fine. I see a small resistor on the differential trace between RSN and load, I also recommend one on the diff trace between R2 and load, just a placeholder of 0Ohm is fine so that you have a knob to turn to filter noise if desired

    Best regards,

    Britton
