MP7742  
2 x 15W Class D Stereo  
Single Ended Audio Amplifer  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP7742 is a Stereo 2 x 15W Class D  
Audio Amplifier. It is one of MPS’ products of  
fully integrated audio amplifiers which  
dramatically reduces solution size by integrating  
the following:  
2 x 15W Output at VDD = 24V into a 4load  
THD+N = 0.03% at 4W, 8Ω  
90% Efficiency at 15W & VDD = 24V  
Low Noise (103µV Typical)  
Switching Frequency Up to 1MHz  
9.5V to 28V Operation from a Single Supply  
Integrated Startup and Shutdown Pop  
Elimination Circuit  
Thermal and Short Circuit Protection  
Integrated Power FETs  
250mpower MOSFETs  
Startup / Shutdown pop elimination  
Short circuit protection circuits  
The MP7742 utilizes a single ended output  
structure capable of delivering 15W per channel  
into 4speakers. MPS Class D Audio  
Amplifiers exhibit the high fidelity of a Class A/B  
amplifier at high efficiencies. The circuit is  
based on the MPS’ proprietary variable  
frequency topology that delivers excellent  
linearity, fast response time and operates on a  
single power supply.  
Pin Compatible with MP7722  
Available in TSSOP20-Exposed Package  
APPLICATIONS  
Flat Panel TV  
Portable Docking Stations  
Surround Sound DVD Systems  
Televisions  
Multimedia Computers  
Home Stereo Systems
