#758 USB 3 Power Adapter Board
Testing a USB 3 Power Adapter Board that can supply a fixed 9, 12, 15, or 20V at up to 5A.
Notes
I just got some “Type C PD2.0 PD3.0 Fast Charge Trigger Polling Detector USB Boost Power Supply Change Module Charger Board Diymore” boards from aliexpress.
These are designed to trick a USB 3.0 power supply to switch into USB-PD mode, allowing the board to be used as a DC power supply at either 9, 12, 15, or 20V (5A max). They use the CH224K USB PD power receiving chip from 南京沁恒微电子股份有限公司 Nanjing Qinheng Microelectronics.
Note: USB PD Revision 3.1 specification is a major update to enable delivering up to 240W of power over full featured USB Type-C cable and connector.
Selecting Output Voltage
The boards all come pre-configured for 12V (with a 0Ω resistor connecting the 12V pad).
They can be re-configured for 9V, 15V, or 20V by moving the 0Ω resistor from the 12V pad to the corresponding pad. This is “relatively” easy to do with a hand soldering iron.
Note: there are other boards available where the output can be selected via DIP switch e.g. Type-C QC AFC PD2.0 PD3.0 to DC Spoof Scam Fast Charge Trigger Polling Detector USB-PD Notebook Power Supply Change Board Module
9V Mode
Re-configured for 9V by moving the 0Ω resistor from the 12V pad to the 9V pad. Output is measuring 8.98V under resistive load.
12V Mode
The boards all come pre-configured for 12V (with a 0Ω resistor connecting the 12V pad). Output is measuring 11.88V under resistive load.
15V Mode
Re-configured for 15V by moving the 0Ω resistor from the 12V pad to the 15V pad. Output is measuring 14.79V under resistive load.
20V Mode
Re-configured for 20V by moving the 0Ω resistor from the 12V pad to the 20V pad. Output is measuring 19.60V under resistive load.
Power Supply
The Power Supply must be designed to deliver the required USB-PD voltages. Many phone chargers can only deliver up to 9V or 12V. For example the Apple 20W charger will only deliver 9V.
For testing here I am using an Essager 65W USB Type C Charger that can deliver up to 20V/3.25A.
