MP7740  
15W Class D Mono  
Single Ended Audio Amplifer  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP7740 is a mono 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:  
15W Output at VDD = 24V into a 4load  
THD+N = 0.05% at 1W, 8Ω  
90% Efficiency at 15W & VDD=24V  
Low Noise (103µV Typical)  
Switching Frequency Up to 1MHz  
9.5V to 36V 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 MP7740 utilizes a single ended output  
structure capable of delivering 15W into 4Ω  
speakers. 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 MP7720  
Available in Tiny 8-Pin SOIC Package  
APPLICATIONS  
Portable Docking Stations  
Surround Sound DVD Systems  
Televisions  
Flat Panel Monitors  
Multimedia Computers  
Home Stereo Systems
