Class D Amplifier

Class D Amplifier

The PowIraudio™ family of integrated power modules for high performance home theatre systems and car audio amplifiers. The new devices integrate a PWM controller and two 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 family 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.

Advantages:
  • Over current protection
  • Thermal shutdown
  • Floating differential Input
  • Clip detection
  • Best-in-class power efficiency and audio performance
  • Reduce component count, simplify design
  • Compatible with single supply or split rail configuration
