Overview
Description
This is a USB-certified reference design for dual-port sourcing ports. This reference design converts a DC input to two USB Type-C® source ports. USB Type-C® source ports support Programmable Power Supply (PPS).
This reference design has two USB Type-C ports, making it a suitable solution for multiport AC adapters.
The standard firmware provided is used for USB-IF certification testing as a Known Good PD Source (with PPS).
USB certification:
TID: 1000181, RTK-251-1BuckBoostConverter2, 60W with PPS Source
The following tool is provided for firmware customization:
