3.3v-3a-step-down-converter-powered-by-usb-c
@maudeve-it

Without using a USB-C PD controller chip, handling communication over the USB cable, USB-C standard allows to get 5V up to 3A through a hardware availability detection. Here I show a design developed on KiCad and made through JLCPCB, powering from a USB-PD source and providing 5V and 3.3 (through a step-down converter) up to 3A.
