IR expands PowIRaudio family

USA: International Rectifier, (IR) announced the expansion of its PowIRaudio family with the introduction of the single channel IR4321M and dual channel IR4322M integrated power modules.

The 60V IR4321M and IR4322M complement the existing product offering and expand the power capability of low load-impedance Class D audio systems in applications including car audio systems, tabletop audio systems, active speakers and musical instruments (with integrated amplifiers).

The combination of an advanced audio controller IC with MOSFETs fully optimized for audio performance results in improved efficiency, THD, and EMI, allowing the IR432xM 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.
