Compact PowIRaudio™ Modules for Class D Amplifier

International Rectifier's Compact PowIRaudio modules are integrated into a single package to offer a highly efficient, compact solution that reduces component count, shrinks PCB size up to 70%, and simplifies Class D amplifier design. The combination of an advanced audio controller IC with MOSFETs, fully optimized for audio performance, results in improved efficiency, THD, and EMI, allowing the IR43XXM family to operate without a mechanical heat-sink over a wide power supply range on either a single or split power supply. High voltage ratings and noise immunity ensure reliable operation over various environmental conditions. The single-channel IR4301M and dual-channel IR4302M offer the flexibility and convenience of building stereo amplifier and multi-channel designs in various channel configurations, while the devices' 5 mm x 6 mm and 7 mm x 7 mm PQFN packages enhance the benefit of utilizing a smaller size of Class D topology.
