IR43x1  
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. A small 5x6 mm PQFN  
package enhances the benefit of smaller size of Class D topology. The IR43x1 are a lead-free, ROHS compliant.

Absolute Maximum Ratings  
Absolute Maximum Ratings indicate sustained limits beyond which damage to the device may occur. All voltage  
parameters are absolute voltages referenced to COM=VN; all currents are defined positive into any lead. The  
Thermal Resistance and Power Dissipation ratings are measured under board mounted and still air conditions.

Recommended Operating Conditions  
For proper operation, the device should be used within the recommended conditions below. The Vss and Vs  
offset ratings are tested with supplies biased at COM=VN, VAA-VSS=9.6V, VCC=12V and VB-VS=12V. All voltage  
parameters are absolute voltages referenced to COM; all currents are defined positive into any lead.
