Appendix A: Enabling DC input power based wireless charging operation on the
REF_WLC_TX15W_C1 reference board
Appendix A: Enabling DC input power based wireless charging operation on the
REF_WLC_TX15W_C1 reference board
This section explains the procedure to enable DC input power-based wireless charging operation on the
REF_WLC_TX15W_C1
reference board.
Do the following procedure to update the reference board and download the firmware which supports DC input
power-based operation, and exercise the wireless charging operation:
Prerequisites:
•
Ensure that the following items provided as part of the
REF_WLC_TX15W_C1
package are available:
−
REF_WLC_TX15W_C1
board (Rev04 and above)
− HPI dongle (Rev01 and above)
− Micro-B USB cable
− USB Type-C cable
•
Ensure that the following are available:
− A Windows-based PC to run the Wireless Charging Configuration Utility. The operating system of Windows
10 or higher is required
− The positive terminal of the DC power supply should connect to the red wire, and the GND terminal of the
DC bench power supply should connect to the black wire. The recommended gauge of the wire is 16 AWG
− Configurable DC bench supply, which can provide 20-V supply and source 3-A of current
− A soldering station
•
Solder the wires to J6 of the reference board as shown in Figure 18

Provision for powering the reference board using bench power supply
Note: The soldering needs to be performed by a qualified technician.
•
Install the software and firmware on the PC
− Contact Infineon Technical support to get the firmware that supports DC input power-based operation
•
Download the firmware onto the
REF_WLC_TX15W_C1
board
a)
Create the USB CC communication-based ( Figure 9 ) or I2C communication-based ( Figure 10 ) hardware
set-up to configure the firmware using Wireless Charging Configuration Utility
