GENERAL DESCRIPTION
The EV0030 is the evaluation board for the
MP7720, a mono 20W Class D Audio Amplifier.
It is one of MPS’ second generation of fully
integrated audio amplifiers which dramatically
reduces solution size by integrating the
following:
180mΩ power MOSFETs
Startup / Shutdown pop elimination
Short circuit protection circuits
Mute / Standby
The MP7720 utilizes a single ended output
structure capable of delivering 20W into 4Ω
speakers. MPS Class D Audio Amplifiers exhibit
the high fidelity of a Class A/B amplifier at
efficiencies greater than 90%. The circuit is
based on the MPS’ AAMTM proprietary variable
frequency topology that delivers excellent
PSRR, fast response time and operates on a
single power supply.
