IR expands PowIRaudio family of integrated power modules

International Rectifier has expanded its PowIRaudio family of integrated power modules with the introduction of the IR4311M and IR4312M.

The 40V IR4311M and IR4312M offer a compact, heatsink-free solution for low power Class D audio applications including tabletop audio systems, active speakers and musical instruments with integrated amplifiers.

The combination of an advanced audio controller IC with MOSFETs fully optimised for audio performance results in improved efficiency, THD, and EMI, allowing the IR43xxM 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.

Additional features common to the family include over-current protection, thermal shutdown, internal/external shutdown and floating differential input. The IR4312M also offers clip detection.

Two reference designs, the IRAUDAMP15 and IRAUDAMP18, featuring the IR4311M and IR4312M respectively are also available.
