MP7748S

2 x 30W Stereo Single Ended

Or 60W Mono BTL Class D Audio Amplifier

DESCRIPTION

FEATURES

The MP7748S is a Class D Audio Amplifier for

driving stereo speakers in single-ended

configuration or a mono speaker in bridge-tied-

load configuration. It is fully integrated audio

amplifier which dramatically reduces solution

size by integrating the following:



9.5V to 36V Operation from a Single Supply

±5.5A Peak Current Output

Output Power at 30V and 10%THD:

- Stereo Single Ended: 2 x 30W into 4Ω Load,

- Bridge Tied Load: 60W into 8Ω Load

THD+N = 0.02% at 1W, 8Ω



200mΩ power MOSFETs

> 90% Efficiency at 10%THD

Low Noise (160μV with SE configuration,

145μV with BTL configuration)

Switching Frequency Up to 1MHz

Integrated Startup and Shutdown Pop

Elimination Circuit

Programmable UVP

Thermal and Short Circuit Protection

Integrated Power FETs

Startup / Shutdown pop elimination

Short circuit protection circuits



The MP7748S is capable of delivering 30W per

channel into 4Ω speaker in single-ended output

structure, or delivering 60W into 8Ω speaker in

bridge-tied-load output structure. MPS Class D

Audio Amplifiers exhibit the high fidelity of a

Class A/B amplifier at high efficiencies. The

circuit is based on the MPS’ proprietary variable

frequency topology that delivers excellent

linearity, fast response time and operates on a

single power supply.



Available in TSSOP28-Exposed Package

APPLICATIONS



Portable Docking Stations

Surround Sound DVD Systems

Televisions

Flat Panel Monitors

Multimedia Computers

Home Stereo Systems

shutdown voltage for each channel by

controlling the UVP node voltage. The default

VDD shutdown (rising threshold) voltage is 8.4V

if the UVP pin is NC.

All MPS parts are lead-free and adhere to the RoHS directive. For MPS green

status, please visit MPS website under Products, Quality Assurance page.

The MP7748S is available in TSSOP28-
