IR4321 & IR4322 Audio Amplifiers

Infineon IR4321 and IR4322 PowIRaudio™ devices integrate a PWM controller and digital audio MOSFETs to form high-performance Class D audio amplifiers. As a result of fully optimized MOSFETs co-packed with a dedicated controller IC, IR4321 and IR4322 amplifiers operate without mechanical heatsink attached in a typical music playback usage. High voltage ratings and noise immunity in the controller IC ensures reliable operation over various environmental conditions. These audio amplifiers are ideal for use in a variety of applications, including home theater systems, docking station audio systems, game consoles, and more.

MERUS™ Class-D Audio ICs

Infineon MERUS™ Class-D Audio ICs are multilevel Class-D audio amplifier solutions featuring an embedded digital power management scheme. These ICs consume significantly less input power (~0.25W) and offer high power output in a small form without compromising the produced sound's quality. A power management algorithm dynamically adjusts the switching frequency and modulation scheme to optimize power loss and EMI across the output power range. Flexible power mode profiles allow users to utilize the multilevel switching technique for very low power loss or high audio performance.

PowIRaudio™ IR43xx Integrated Power Modules

Infineon PowIRaudio™ Compact Integrated Power Modules are designed for high performance home theater systems and car audio amplifiers. They each integrate a PWM controller and two digital audio power MOSFETs in a single package, forming a high performance Class D audio amplifier. These integrated power modules offer a highly efficient, compact solution that reduces component count, shrinks PCB size up to 70%, and simplifies Class D amplifier design.
