Introduction
This document is a user guide for the
WLC1115 MP-A11 15-W wireless power transmitter reference solution
(
REF_WLC_TX15W_C1
)
. This solution consists of the reference board, firmware, and software utility called as
the Wireless Charging Configuration Utility.
Infineon’s
WLC1115 based 15-W wireless power transmitter reference board
REF_WLC_TX15W_C1
is a highly
integrated, Qi compliant transmitter design with an MP-A11 type transmitter coil. The
REF_WLC_TX15W_C1
board works with WPC-certified wireless receivers by taking power from a type-C PD adapter. The input voltage
will be automatically configured to 9-V, 15-V or 20-V based on load power requirements of receiver and PD
capability. A two-switch buck regulator topology, powered by PD input, is used to provide the regulated input
voltage to the full-bridge inverter, driving the resonance tank (resonance capacitor and transmitter coil).
The WLC1115 can support variable inverter input voltage control and variable WPC operating frequencies
control for inverter to optimize operation with WPC receivers. For the MP-A11 transmitter coil, variable inverter
input voltage control is used by the WLC1115. WLC1115 has integrated gate drivers for the buck and inverter
power supplies necessary for wireless transmitter applications. WLC1115 supports a wide input voltage range
and offers many programmable features for creating distinct wireless transmitter solutions.

to understand the capabilities of the WLC1115 controller in more detail.
Note: Infineon offers Qi v1.3.2 EPP certified reference solution with several configurable parameters via the
Wireless Charging Configuration Utility for system-specific enhancements. However, the end product Qi
certification is the product manufacturer
’s
responsibility.
