IR4311 Description

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 IC ensures reliable operation over various environmental conditions.
