Description
The IR43x2 integrates 2 channel 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 IR43X2
operates 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. A small 7x7 mm
PQFN package enhances the benefit of smaller size of Class D topology. The IR43X2 series is a lead-free, ROHS
compliant.
