QUICK START GUIDE
Wired and Wireless Charging Solution
REF_TX15W_PD60W_N1
This document is a quick start guide for the REF_TX15W_PD60W_N1 board. This
solution combines wired and wireless charging functions in parallel or individually.
This solution uses Infineon's WLC1115 wireless charging transmitter IC and the
EZ-PD™ CCG7SC USB-C IC. The solution provides power to a wireless power receiver
and to a USB-C sink device using smart power sharing to manage power for each load.
The solution manages the source PD power adapter input by adjusting the wireless
and wired output power levels based on the input power source capability.

1. Reference board features
The following are the main features of the reference board:
–Wide input voltage ranges, from 9 V to 24 V.
–Wireless charging supports BPP, EPP, and up to Qi 1.3.3 compatible.
–Wire charging supports dual modes: One is PDO mode , the other is PPS mode. PDO
mode supports 3 A with 5 V, 9 V, 12 V, 15 V, 20 V, and 60 W max. And PPS mode
supports 3 A from 3.3 V to 16 V.
–Built-in Infineon's proprietary bypass technology and power sharing technology
to maximize the power distribution and maximize power levels to each output
at optimal eiciency.
–When the PDO capacity is greater than 45 W, it supports notebook charging.
–LED indicator to alert users of faults and status.

2. Before you start
Ensure that all communication pins are shorted with jumpers.
–P2 connector: pin7 is shorted to pin8 with a jumper and pin9 is shorted to pin10
with a jumper.
–P4 connector: shorted with a jumper.
3. Power Sharing Functions
This solution has Infineon's unique smart power sharing technology and bypass
technology. When wireless charging and wired charging are used at the same time,
smart power sharing technology is enabled to maximize power utilization.
Infineon's unique bypass mode is used to improve the eiciency of PD.
When the PDO capacity is greater than 45 W, it supports notebook charging.

4. PD power bypass function
When only PD, or the output of PD is at the same voltage as the USB-IN input the FW
automatically enables unique Bypass function to improve PD eiciency.

Safety information
See the following table for system states of the transmitter and corresponding status
LED indications on the transmitter (REF_TX15W_PD60W_N1).
The CCG7SC LED has two states of operation: solid blue light means that the PD output
capacity of CCG7SC is greater than 45 W (laptop charging capable) and a solid red light
means that the PD output capacity of CCG7SC is less than 45 W.
The REF_TX15W_PD60W_N1 reference board is intended for use as an evaluation
platform for hardware or software in a laboratory environment. The board is an open-
system design, which does not include a shielded enclosure. Due to this reason, do not
use this board near any medical equipment or RF devices. Attaching additional wiring to
this product or modifying the product operation from the factory default may aect its
performance and cause interference with other apparatus in the immediate vicinity.
If such interference is detected, suitable mitigating measures must be taken.
The REF_TX15W_PD60W_N1 reference board contains ESD-sensitive devices.
Electrostatic charges readily accumulate on the human body and any equipment, which
can cause a discharge without detection. Permanent damage may occur to devices
subjected to high-energy discharges. Proper ESD precautions are recommended to
avoid performance degradation or loss of functionality. Store unused
REF_TX15W_PD60W_N1 reference boards in the protective shipping package.
