This document is a user guide for the
( ). This solution consists of the reference board, firmware, and software utility called the
REF_WLC_TX50W_N1
Wireless Charging Configuration Utility.
Infineon's WLC1150-based 50-W wireless power transmitter reference board
integrated, Qi-compatible transmitter design with an MP-A2 type transmitter coil.

power from a Type-C PD adapter and delivering up to 50 W power. The input voltage will be automatically
configured to 20 V. It can also be powered up with fixed input DC supply of 20 V/4 A. Input supply is used to
power up the full-bridge inverter driving the resonance tank (resonance capacitor and transmitter coil). The
inverter controls the output power flow by changing the switching frequency and duty.

C PD adapter and delivering up to 15 W power. The input voltage is automatically configured to 12 V or 15 V
based on Type-C PPS/PD contract capability. Input supply is used to power up the full-bridge inverter driving
the resonance tank (resonance capacitor and transmitter coil). The inverter controls the output power flow by
varying the switching frequency and duty cycle.
WLC1150 has integrated gate drivers for the buck and inverter power supplies necessary for wireless
transmitter applications. Buck controller is being used to control the fan integrated with
WLC1150 supports a wide input voltage range and offers many programmable features for creating distinct
wireless transmitter solutions.

of 127.7 kHz and 50% duty by taking power from a Type-C PPS adapter. It requires a Type-C PPS adapter. The
input voltage supplied by the PPS adapter will be controlled by WLC1150, by input voltage configuration to
control the output power flow.
