Monolithic Power Systems MP7751GF

Description

The EV7751-F-00A is the evaluation board for the MP7751, a 20W stereo BTL Fix Freuquency Class D Audio Amplifier. It is one of MPS’ products of fully integrated audio amplifiers which dramatically reduce solution size byintegrating the following:

• 240mΩ power MOSFETs

• Startup / Shutdown pop elimination

• Short circuit protection circuits

• Advanced EMI performance

The MP7751 utilizes Bridge Tied Load output structure capable of delivering stereo 20W into 8Ω speakers. It features in automatic shutdown function which c an save power in battery-used system. The PLIMIT function is useful for limiting total output power by simply adjust a DC reference voltage at PLIMIT pin. MPS Class D Audio Amplifiers exhibit the high fidelity of aClass A/B amplifier at high efficiency.

Features

• 20W Stereo BTL Output at VDD = 18V into 8Ω loads
• 9.5W Stereo BTL Output at VDD = 12V into 8Ω loads
• Better than 90% Efficiency at 9.5W x 2 and VDD=12V with 8Ω load, Stereo
• Low Noise (120μV Typical)
• 5V to 26V Operation from a Single Supply

Typical applications

• Home Theater
• Active Speakers
• TV
• DVD Receiver
