DESCRIPTION  
FEATURES  
The MP78730 is a stereo 2 x 20W Class D  
Audio Amplifier. It is one of MPS’ second  
generation fully integrated audio amplifiers  
which dramatically reduces solution size by  
integrating the following:  
2 x 20W Output at VDD = 24V into a 4load  
THD+N = 0.06% at 1W, 8Ω  
93% Efficiency at 20W  
Low Noise (190μV Typical)  
Switching Frequency Up to 1MHz  
9.5V to 24V Operation from a Single Supply  
Integrated Startup and Shutdown Pop  
Elimination Circuit  
Thermal and Short Circuit Protection  
Integrated 180mSwitches  
Mute/Standby Modes (Sleep)  
Thermally Enhanced 20-Pin TSSOP  
Package with Exposed Pad  
180mpower MOSFETs  
Startup / Shutdown pop elimination  
Short circuit protection  
Mute / Standby  
The MP78730 utilizes a single ended output  
structure capable of delivering 2 x 20W into 4Ω  
speakers. MPS Class D Audio Amplifiers exhibit  
the high fidelity of a Class A/B amplifier at  
efficiencies greater than 90%. The circuit is  
based on the MPS’ proprietary variable  
frequency topology that delivers low distortion,  
fast response time and operates on a single  
power supply.
