  RE: WEBENCH® Tools/TPS54140A: TPS54140A error in feedback resistor

  Hi Lin_Charles, You are correct that 52.5K is the ideal value. I looked at BOM tab of the design and tried to change the value and it shows the target resistance value to be 52.5K. The 56.2K is the closest value to that target that is the Webench library...
