200 W stereo integrated Class D amplifier, 2-channel, QFN-42

MA5332MS , 200W Stereo, Integrated Class D Amplifier

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 RDS(ON) MOSFETs. Like its predecessor, IR43x2M, it includes standard Class D protection 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.
