USB C 3A/5V charger. Power delivery IC needed?

[Pineapple Dan]

Would I need something like this: https://www.diodes.com/products/power-management/ac-dc-converters/secondary-side-controllers-and-switchers/secondary-side-protocol-decoder/part/AP43770#tab-overview

or would there be a way to get 3A using only resistors? Have been searching for a while but can't see the wood from the trees. I am hoping to put this onto a PCB with USB C receptacle and power it with a TI LM2676 or 22679 regulator, not too pushed about being able to supply other voltages USB 3 supports for now
