MA5332MS 200W Stereo, Integrated Class D Amplifier Features 2 channel analog input Class D audio amplifier in a small 7x7mm package Very low R at 24.4 m typical, enabling heatsink-less operation at 2x100W at 4 DS(ON) 95% efficiency Class D at 2x200W at 4 PG- IQFN-42 Split or single power supply capable Differential or single-ended input Multiple configuration options: 2xSE, BTL, PSE (Parallel Single-Ended) Over-current, over-temperature and under-voltage protections with self-reset feature Start/stop click noise reduction Clip and Fault reporting outputs Applications Multi-channel home theatre system Studio monitor Active speaker Soundbar subwoofer Marine amplifier Aftermarket car audio system General-purpose audio power amplifier Total Harmonic Distortion Product validation Qualified for standard applications according to the relevant tests of J-STD-020 and JESD22. Product type Package MA5332MS 7x7mm PG- IQFN-42 Description The MA5332MS offers the same or higher output power than monolithic alternatives without heatsink and 50% less footprint. This MCM (multi-chip module) solution integrates 2 channel PWM controller, high voltage gate driver, and 4 low R MOSFETs. Like its predecessor, IR43x2M, it includes standard Class D protection DS(ON) features for reliable operation over various environmental conditions. As a powerful upgrade to IR43x2M and other monolithic solutions, MA5332MS 7x7 mm PG- IQFN-42 package showcases the benefit of small footprint, high power density, and heatsink-less operation.
