MP7741DQ-LF-P

The MP7741 is a mono 10W Class D Audio Amplifier. It is one of MPS’ products of fully integrated audio amplifiers which dramatically reduce solution size by integrating the following: 250m? power MOSFETs Startup / Shutdown pop elimination Short circuit protection circuits The MP7741 utilizes a single ended output structure capable of delivering 10W into 8? 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. MP7741 features programmable VDD shutdown voltage by controlling the UVP node voltage. The default VDD shutdown voltage is 8.4V if the UVP pin is NC.

10W Output at VDD = 24V into a 8? load THD+N = 0.02% at 1W, 8? 94% Efficiency at 10W & 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 Programmable UVP Thermal and Short Circuit Protection Integrated Power FETs Available in 10-Pin QFN3x3 Package
