REF_WLC_TX15W_M1 Overview
A wireless charging transmitter reference design is a complete evaluation platform used to develop and verify the power-transfer, communication, control, and protection functions required for Qi-compatible charging products. In the broader product hierarchy, wireless power transmitter solutions sit within wireless power systems, power-management electronics, and semiconductor-based development platforms. REF_WLC_TX15W_M1 provides a practical implementation reference rather than a simple discrete component.
The verified design features identify the board as a programmable 15 W Qi2 MPP transmitter with an optimized form factor of less than 43 mm diameter. It uses WLC1115 as the wireless transmitter controller and includes USB Power Delivery, DC-DC conversion, and secure wireless-charging authentication. The board also supports ModusToolbox code examples, helping developers configure the transmitter and accelerate firmware integration.
Qi2 MPP adds magnetic alignment guidance for compatible receivers, while backward support for Qi BPP allows 5 W operation with receivers that do not implement MPP. The integrated authentication device, identified in Wireless Power Consortium material as SLS32AIA020U3, adds a security-oriented function to the transmitter platform. Infineon describes the design as highly integrated and optimized for compact form factors.
Typical uses include development of Qi2 phone and accessory chargers, USB-C wireless power products, compact embedded charging modules, and Qi2-compatible receiver testing. The board is useful for prototyping, firmware evaluation, power-transfer validation, and reference-design adaptation. It is not merely a generic 15 W power board; its value lies in the combination of Qi2 MPP, USB-PD, DC-DC conversion, authentication, and software support.
For system integration, developers should use the manufacturer’s hardware design guidance and current board documentation rather than treating the reference board as a production-certified product. The verified material does not provide a complete electrical schematic, pinout, input-current limit, efficiency curve, operating-temperature range, or compliance declaration. Those values require confirmation from the relevant Infineon documentation before a production design is released.
This page synthesizes the verified Infineon product description, solution-brief data, Wireless Power Consortium listing, and distributor information into an engineering-oriented overview. It emphasizes the board’s verified Qi2 MPP, 15 W output, 5 W BPP compatibility, less-than-43-mm form factor, WLC1115 controller, integrated USB-PD and DC-DC functions, and security-device role. Manufacturer documentation remains the authority for final electrical, mechanical, thermal, firmware, and compliance decisions.

Typical Applications
REF_WLC_TX15W_M1 is suitable for 6 applications: Qi2 Phone Charging Prototype, USB-C Wireless Charger Development, Qi2 Accessory Charger, Receiver Compatibility Testing, Embedded Wireless Charging Module, Wireless Charging Power-Control Lab.
Qi2 Phone Charging Prototype
REF_WLC_TX15W_M1 fits Qi2 phone-charger development because the verified board supports 15 W Qi2 MPP operation and retains 5 W Qi BPP compatibility. Engineers can use the WLC1115-based platform to evaluate transmitter firmware, receiver negotiation, magnetic alignment, and USB-PD input behavior before integrating the architecture into a compact product. The less-than-43-mm form factor is useful when the transmitter must fit inside a constrained enclosure. The reference board is a development platform, so production designs should verify coil geometry, thermal performance, input limits, and certification independently.
Recommended
USB-C Wireless Charger Development
The board is suitable for USB-C wireless charger prototypes because Infineon identifies integrated USB-PD functionality in the reference solution. That input architecture can help developers connect a modern USB-C power source while evaluating the WLC1115 transmitter-control and DC-DC stages. The verified material supports Qi2 MPP at 15 W and BPP at 5 W, enabling one platform to test both newer and established receivers. Before productization, engineers must confirm input voltage, current, protection, thermal limits, and cable requirements from the latest board documentation.
Recommended
Qi2 Accessory Charger
REF_WLC_TX15W_M1 can serve as the starting point for compact Qi2 accessory chargers where 15 W MPP operation is useful. The WLC1115 controller handles the programmable transmitter side, while the reference board demonstrates integration of DC-DC conversion and authentication. Its less-than-43-mm form factor supports mechanical exploration for small enclosures, although the final coil, ferrite, shielding, and thermal design remain application-specific. Use the board to validate receiver compatibility and power-transfer behavior before committing to a custom PCB.
Recommended
Receiver Compatibility Testing
The board is useful for receiver compatibility testing because it supports Qi2 MPP receivers at 15 W as well as Qi BPP receivers at 5 W. This dual-profile capability lets engineers compare negotiation behavior, power levels, alignment sensitivity, and fault handling across receiver classes. The WLC1115-based design also provides a programmable platform for transmitter configuration through ModusToolbox examples. For reliable lab results, define the input source, receiver fixture, coil alignment procedure, thermal limits, and logging method before comparing alternatives.
Recommended
Embedded Wireless Charging Module
The optimized reference board can inform embedded wireless charging modules for products with limited internal space. Its less-than-43-mm diameter and integration of WLC1115, USB-PD, DC-DC, and OPTIGA Trust Charge provide a useful starting architecture for compact modules. The design should not be treated as a production module without checking the coil and ferrite implementation, power conversion ratings, enclosure effects, thermal behavior, and EMC requirements. ModusToolbox support can accelerate firmware bring-up and profile configuration.
Recommended
Wireless Charging Power-Control Lab
REF_WLC_TX15W_M1 supports laboratory evaluation of wireless power-control behavior across 15 W Qi2 MPP and 5 W Qi BPP operating modes. Engineers can observe how USB-PD input conditions, transmitter control, DC-DC conversion, and authentication cooperate during receiver negotiation. The board’s ModusToolbox examples help establish a repeatable firmware baseline, while the compact format allows it to be mounted in a representative fixture. Production measurements should use calibrated instruments and explicitly documented thermal, alignment, and environmental conditions.

Key Differentiators
- Qi2 MPP support with 15 W wireless output (vs REFWLCTX15WC1)
- Backward-compatible 5 W BPP operation (vs Qi2-only receiver designs)
- Integrated security-oriented authentication (vs REF_WLC_TX15W_C1)
- Compact form-factor reference architecture (vs Larger conventional transmitter boards)
Design Notes
Use the verified 15 W Qi2 MPP capability as the design ceiling, not as a guaranteed continuous output without checking the input source, USB-PD contract, coil, thermal path, and board documentation. For a 5 V-class test setup, the WLC1115 community result referenced in the verified search data indicates that power transfer in the related 9 V transmitter solution occurs at 9 V, so input negotiation should be treated as an explicit configuration decision. Do not infer a fixed input voltage from the target board’s 15 W output rating.
Treat the wireless transmitter as a power-electronics layout problem rather than only a controller layout problem. Keep the USB-PD input path, DC-DC power stage, coil driver, sensing network, and WLC1115 ground return carefully partitioned. Preserve the manufacturer’s recommended high-current copper widths, decoupling placement, thermal-via pattern, and coil geometry. The verified public data does not provide the complete REF_WLC_TX15W_M1 schematic, so exact trace and component values must come from current Infineon documentation.
Thermal validation is essential because the board transfers up to 15 W wirelessly and also includes USB-PD, DC-DC, and authentication functions. Measure the controller, power-stage components, coil, input connector, and authentication device during repeated charging and worst-case receiver loading. Use the verified less-than-43-mm form factor as a mechanical starting point, but do not assume that compact size eliminates the need for copper spreading, airflow, enclosure validation, or thermal derating.
The most important integration risk is treating a reference board as a production-ready module. Confirm the required USB-C input profile, receiver negotiation behavior, coil and ferrite implementation, firmware configuration, authentication provisioning, fault handling, and applicable wireless-charging certification. Also avoid confusing Qi2 MPP with Qi BPP: the target board supports 15 W MPP and 5 W BPP, while related Infineon boards may use different Qi versions or profiles.
Wireless power evaluation requires controlled alignment and repeatable measurement setup. Define receiver placement, foreign-object conditions, input-source limits, cable configuration, and measurement bandwidth before comparing REF_WLC_TX15W_M1 with another design. Use the ModusToolbox examples as a controlled firmware baseline and preserve controller configuration logs. Changes to coil geometry, ferrite placement, filtering, or power-stage layout can alter coupling, negotiation, efficiency, and thermal behavior.
Compliance Information
The verified data identifies Qi2 and Qi BPP support but does not provide RoHS, REACH, lead-free, halogen-free, conflict-minerals, automotive, safety, or regulatory certification declarations. Compliance must be confirmed from current Infineon documentation for the exact board and ordered MPN.
