MP7770

2 x 45W Stereo Single-Ended

or 90W Mono BTL Class-D Audio Amplifier

The Future of Analog IC Technology

DESCRIPTION

FEATURES

MP7770 is an analog class-D audio amplifier

that can drive either stereo speakers in single-

ended configuration or a mono speaker in a

bridge-tied-load configuration. It is part of

MPS’s family of fully-integrated audio amplifiers

that dramatically reduce footprint size by

integrating:



9.5V-to-36V Operation from a Single Supply

±8.5A Peak Current Output

Output Power at 36V and 10%THD:

- Stereo Single-Ended: 2 x 45W into 4ꢀ Load,

- Bridge-Tied Load: 90W into 8ꢀ Load

THD+N = 0.03% at 1W, 8ꢀ

> 90% Efficiency at 10%THD

Low Noise

Switching Frequency of up to 1MHz

Integrated Startup and Shutdown Pop

Elimination Circuit



100mΩ power MOSFETs

Startup/Shutdown pop elimination

Short-circuit protection circuits



Programmable UVP

The MP7770 is capable of delivering 45W per

channel into 4Ω speaker in single-ended output

structure, or delivering 90W into 8Ω speaker in

bridge-tied-load output structure under 36V

VDD. 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.

Thermal and Short-Circuit Protection
