Wireless charging uses electromagnetic fields to transfer power from a transmitter to a receiver
to charge the battery of the end-application.
Infineon’s broad selection of components helps you to master your design challenges for resonant
and inductive solutions. As a member of the Wireless Power Consortium and the AirFuel Alliance,
Infineon is dedicated to actively shape the trends of tomorrow.
Choose Infineon to solve your application requirements:
›
High performance MOSFETs, ICs and MCU at optimum price/performance ratio thanks to cost-
eective packages and leading, reliable and mature silicon technology
›
High power density in small designs: Enabling the lowest switching and conduction losses in
smallest packages for MOSFETs and power stage
›
Smallest possible package size (2 x 2, 3 x 3 half-bridge) for low power MOSFETs 30 V-250 V
›
Highest eiciency: In hard switching topologies, enjoy low switching losses thanks to low input
and output capacitances
Infineon is working on its own medium voltage GaN technology and will bring it to the market with
a significant performance increase over silicon MOSFETs and at the same level of reliability.
