PowIRaudio™ IR43xx Integrated Power Modules

Infineon PowIRaudio™ Compact Integrated Power Modules are designed for high performance home theater systems and car audio amplifiers. They each integrate a PWM controller and two digital audio power MOSFETs in a single package, forming a high performance Class D audio amplifier. These integrated power modules offer a highly efficient, compact solution that reduces component count, shrinks PCB size up to 70%, and simplifies Class D amplifier design.
