Audio controller IC offers improved efficiency

The PowIRaudio family of devices integrates PWM controller and digital audio power MOSFETs in a single package to offer a highly efficient, compact solution that reduces component count, shrinks PCB size up to 70 percent 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 PowIRaudio family to operate without a mechanical heatsink 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 IR4311M and dual channel IR4302M and IR4312M devices offer the flexibility and convenience of building stereo amplifier and multichannel designs in various channel configurations, while the devices’ 5x6 mm and 7x7 mm PQFN packages enhance the benefit of utilizing a smaller size of Class D topology.

International Rectifier (IR) is a pioneer and world leader in advanced power management technology, from digital, analog and mixed-signal ICs to advanced circuit devices, power systems and components. The world's leading manufacturers of computers, appliances, automobiles, consumer electronics and defense systems rely on IR technology to drive the performance and efficiency of their products.
