The EV7770-F-01A is a single-ended configuration evaluation board designed to demonstrate the capabilities of the MP7770, an analog Class-D audio amplifier that can deliver 45W per channel to a 4Ω speaker under a 36V input voltage (V_DD). It is part of MPS’s family of fully integrated audio amplifiers that dramatically reduce solution size by integrating 100mΩ power MOSFETs, start-up/shutdown pop elimination, and short-circuit protection (SCP) circuits.

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

The MP7770 is available in a TSSOP-28EP package.
