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 by

integrating 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 can 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 a

Class A/B amplifier at high efficiency.
