When comparing the datasheet and webench for the TPS54531 Rcomp and Ccomp are flipped. Which design should be used?

What's you work condition? 8~28Vin ,5Vout/5A?

The value in DS and WEBENCH are flipped is because the LC is different, so the value of the Rcomp and Ccomp are not same. Two designs are all OK.

Hi Kate,

Are you referring to the series RC connected on comp pin? They are just a RC to create a pole and zero to tune control loop. If they are connected to comp pin in series, it is fine. It does not matter whether R on top or C on top. Thanks!

Best,
Anthony
