Typical Application for IR4311 Integrated Digital Audio Amplifier. The IR43x1 integrates PWM controller and digital audio MOSFETs forming a high performance Class-D audio amplifier. As a result of fully optimized MOSFETs co-packed with a dedicated controller IC, the IR43X1operates without mechanical heatsink attached in a typical music playback usage. High voltage ratings and noise immunity in the controller ensures reliable operation over various environmental conditions
