IR4311MTRPBF

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 heat sink attached in a typical music playback usage. High voltage ratings and noise immunity in the controller IC ensures reliable operation over various environmental conditions. A small 5x6 mm PQFN package enhances the benefit of smaller size of Class D topology. The IR43x1 are a lead-free, ROHS compliant.
