    Jeff,

    The TPS54336A has the Re-Comp feature. Simply click on the Re-Comp button and enter the Compensation Designer. If you only want to change Ccomp, use the Manual tab and enter the value for Ccomp under the Edit Components option for the Compensation parameters. Then, look at the results you get to see if that will suit your needs.

    You can also use the automatic mode to target performance characteristics. None of the changes are applied to the design until you hit the Apply changes to design green button.
