200W Stereo, Integarted Class D Audio Amplifier REF_MA5332BTLSPS

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.
