MP7770

MP7770 is an analog class-D audio amplifier that can drive either stereo speakers in single-ended configuration or a mono speaker in a bridge-tied-load configuration. It is part of MPS’s family of fully-integrated audio amplifiers that dramatically reduce footprint size by integrating: • 100mO power MOSFETs • Startup/Shutdown pop elimination • Short-circuit protection circuits The MP7770 is capable of delivering 45W per channel into 4O speaker in single-ended output structure, or delivering 90W into 8O speaker in bridge-tied-load output structure under 36V VDD. MPS’s class D audio amplifiers exhibit the high fidelity of a Class A/B amplifier at higher efficiencies. The circuit is based on the MPS’s proprietary variable-frequency topology, which delivers excellent linearity, fast response time and operates from a single power supply.
