    Hello Edward,

    We do not have a buck converter with integrated PD functionality

    We use the LM3489 on our TPS65987DEVM which has a bypass mode that allows you to pass through a barrel jack or central supply. You can negotiate a 20V contract with the TPS65987D which will then control the LM3489 to pass through a 20V supply to VBUS.

    What application are you designing for where you need a PD controller to source this much power? The cable you use also must be taken into account as the amount of power a PD controller can supply will be limited to the cable capabilites

    You can also refer to the Power Duo source board for reference
