Type-C to DC5.5 PD/QC decoy

TypeC PD/QC decoy, based on HUSB238 chip

RI sets the current and RV sets the voltage. Please refer to the HUSB238 data sheet for details.

Voltage setting (choose one of two):

1. Without soldering the RV, adjust the decoy voltage to 5/9/12/15/20V through the DIP switch (QC only supports 5~12V). See the silk screen for the corresponding configuration of each voltage.
2. Do not solder the DIP switch and the two 10K and 15K resistors, solder the RV setting voltage

Overvoltage and undervoltage protection (optional): If overvoltage and undervoltage protection is not required, do not solder R4, R5, Q2, and short J1

DC output: The notch on the PCB can be soldered with a DC5.5mm plug as shown in the picture, and the data line can be used as a decoy line.

You can also connect this module to both ends of the C-to-C line and use it as a DC line.

Note: Do not use voltage exceeding 25V, and do not send inappropriate voltage to the device.
