The new IR Class D audio chipset audio driver IC with IRS2092S
 

Power management technology vendors - International Rectifier Corporation (International Rectifier, referred to as IR) has introduced the use of IRS2092S integrated audio driver IC chip set, with protection of PWM (PWM) switch and IR MOSFET integrated features such as digital audio. The chipset aimed at the middle from 50W to 500W power, high performance Class D audio amplifier applications, such as home theater, home stereo, active speaker, musical instruments and professional audio applications.
The formation of new chip Class D audio solution than the Class AB design a smaller area. For example, applications in the 100W, IRS2092S IC and IRF6645 DirectFET MOSFET can be reduced by 60% of the footprint than the typical 20% reduction in material form the number of devices.
New audio driver IC architecture based on half bridge topology, integrated Class D design to achieve the required four basic functions, including error amplifier, PWM comparator, gate driver, and robust protection circuitry. Therefore, this compact 16-pin IC with a high noise resistance, can reduce the start and end of the broken sound, while greatly reducing the number of overload protection such as a very complex and expensive design work.
IRS2092S The main features include: frequency up to 800kHz analog PWM modulator with self-reset control, programmable bidirectional over-current protection (OCP), under voltage lockout protection (UVLO), and can be extended programmable preset power design dead time.

Features
• Integrated analog input Class D audio amplifier
Driver in a small 16-pin package

Thank!

I have used the irs2092 successfully to produce 750watts peak but I had to add gate drivers (TC4420)
Care has to be taken with decoupling and layout.

I do not know. I also got from the IR2092 PDF
