The USB-C Power Delivery Adapter is a module providing 12V 55W continuous power output from a single USB-C PD power supply. The board was designed as a power option for Antmicro's Thunderbolt to GPU Adapter in stand-alone operation.
The design files were prepared in KiCad 9.x.
To operate properly, the PD sink controller must be first programmed.
The QWIIC connector is dedicated for I2C connection with STUSB4500.
Programming instructions and tools can be found on the manufacturer's website.
Below, you can find the recommended profile for the PD sink:
PDO1: 5V (+15%/-5%), 1.5A
PDO2: 20.0V (+10%/-20%), 3.0A
PDO3: 20.0V (+10%/-20%), 4.5A
PDO Number: 3
Flex Current: 2.0
External Power: False
USB Communication Capable: False
Configuration OK GPIO: 2
GPIO Control: 1
Enable Power Only Above 5V: False
Request Source Current: False
Factory Default: False
The USB-C Power Delivery Adapter must be powered from a USB PD power supply with the following features:
