The EV7770-F-00B is the BTL (Bridge Tied Load) configuration evaluation board for the MP7770GF, which can deliver 90W into 8Ω speaker under 36V VDD. It is one of MPS’ products of fully integrated audio amplifiers which dramatically reduce solution size by integrating:

• 100mΩ power MOSFETs
• Startup/Shutdown pop elimination
• Short-circuit protection circuits

MPS’s class D audio amplifiers exhibit the high fidelity of a Class A/B amplifier at higher efficiencies. The circuit is based on the MPS’s proprietary variable-frequency topology, which delivers excellent linearity, fast response time and operates from a single power supply.
