20W Wide-Input Wireless Charging TX Module | 9–32V OEM Integration

20W transmitter platform for wide-input systems

This TX module is a practical starting point for products powered from a 12V or 24V rail. It is intended for engineering integration rather than drop-in use without validation: the enclosure, coil-to-surface distance, nearby metal, magnets, cooling and receiver all affect power transfer and FOD behaviour.

Reference configuration

What must be reviewed before integration

• Available input power and transient behaviour of the host power rail.
• Target receiver, required delivered power and permitted charging time.
• Coil size, alignment tolerance, surface thickness and surrounding materials.
• Thermal path, ambient temperature and continuous-duty requirements.
• EMC/EMI, FOD and communication requirements for the target market.

Customization and project deliverables

PCB shape, connectors, coil geometry, firmware behaviour and host communication can be reviewed as part of an OEM project. Agree the required files at project start; available deliverables can include schematic and PCB data, BOM, firmware configuration, integration guidance, test records and production-test requirements.

Request an engineering review

Send the input-voltage range, receiver requirement, available space, coil gap, enclosure material, expected volume and target certification. CowinLink will confirm whether this platform is suitable or whether a new architecture is required.
