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

FEATURES

• 20W Output at VDD = 24V into a 4Ω load

• THD+N = 0.04 at 1W, 8Ω

• 93 Efficiency at 20W

• Low Noise (190µV Typical)

• Switching Frequency Up to 1MHz

• 9.5V to 24V Operation from a Single Supply

• Integrated Startup and Shutdown Pop Elimination Circuit

• Thermal Protection

• Integrated 180mΩ Switches

• Mute/Standby Modes (Sleep)
