About This Product

■Summary

The MP7747 is a mono 20W class D audio amplifier. This is one of MPS' fully integrated audio amplifier products, which significantly reduces solution size by integrating: 250mΩ power MOSFET, pop noise rejection during start-up/shutdown, and short-circuit protection circuitry. The MP7747 utilizes a single-ended output structure capable of delivering 20W to a 4Ω speaker. MPS' Class D audio amplifiers exhibit the high efficiency and high fidelity of Class A/B amplifiers. The circuit is based on MPS's proprietary variable frequency topology, which provides excellent linearity, fast response time, and operates from a single supply. The MP7747 has a programmable VDD shutdown voltage by controlling the UVP node voltage. When the UVP pin is NC, the default VDD UVP voltage (rising threshold) is 8.4V.

■Features and benefits

・20W output at VDD = 24V into 4Ω load ・THD + N = 0.02% (1W, 8Ω) ・91% efficiency at 20W & VDD = 24V ・Low noise (103μV standard) ・Switching frequency up to 1MHz ・9.5V to 36V operation with single power supply ・Integrated pop noise removal circuit during startup and shutdown ・Programmable UVP ・Thermal and short circuit protection ・Power FET integration ・Provided in 10-pin QFN3 x 3 package

■Available product numbers

・MP7747DQ-LF-P MP7747DQ-LF-Z ・Part numbers ending in P and Z are the same part. P and Z indicate reel size only
