Semtech has extended its LinkCharge wireless charging platform to higher-power industrial applications, claiming its LinkCharge 20 Series as the only inductive wireless charging system beyond 15 watts that is currently available.

The LinkCharge 20 Series includes two high-power wireless charging transmitter and receiver evaluation platforms for industrial applications supporting up to 20W using magnetic, inductive-based wireless charging technology. It is the only currently available inductive wireless charging system that supports up to 20W using a proprietary protocol for communication between the transmitter and the receiver. Industrial equipment manufacturers can use the LinkCharge 20 to test wireless power in next-generation applications such as power tools, appliances, medical instruments and automation systems. The company positions LinkCharge 20 as specifically tailored to industrial applications. Features include DC-DC efficiency at [up to] 85%; and a flexible, programmable firmware-based solution to accommodate the evolution of industry standards
