Infineon Technologies Turnkey Closed Loop Class-D Amplifier Modules

Infineon Technologies Turnkey Closed Loop Class-D Amplifier Modules are self-contained 200W-per-channel devices designed for manufacturers of powered loudspeakers, stand-alone stereos, and multi-channel amplifiers. Developed around the enhancement mode GaN-on-silicon power transistors and next-generation driver technology, combined with high-quality output filters, these modules deliver high audio quality and sound. A heat sink is not required under normal conditions. Thermal protection is provided for worst-case thermal environments, and 96% efficiency reduces heat and system size.

The evaluation modules provide a comprehensive GaN high-performance Class-D Amplifier solution with high efficiency, reduced heat, reduced system size and weight due to the absence of a heat sink, graceful protection, auto recovery, and easy integration with switched-mode power supply solutions. This comprehensive solution from GaN Systems enables audio systems designers across markets to mix and match designs and maximize performance for specific industries.
