MP7752

18V, 2x15W Stereo BTL, Fixed Frequency,

Inductorless Class-D Audio Amplifier

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP7752 is an analog input inductorless

class-D audio amplifier, which drives stereo

speakers in bridge-tied-load configuration. It is

a fully integrated audio amplifier, which reduces

solution size dramatically. It integrates 240mΩ

power MOSFETs and short-circuit protection

circuits, and it features start-up/shutdown pop

elimination and advanced EMI performance.

Also, it is inductorless while passing the EMC

test.



5V to 18V Operation from a Single Supply

±5A Peak Current Output

Output Power:

9.5W/Channel at 12V, 8ꢀ Load, 10%THD

15W/Channel at 16V, 8ꢀ Load, 10%THD

90% Efficiency with 8ꢀ Load, 10%THD,

1kHz, 12V Supply Voltage



240mꢀ Power MOSFETs

Start-UP/Shutdown Pop Elimination

Short-Circuit Protection Circuits

Inductorless Topology

Advanced EMI performance

All Switches Current Limited

Internal Under-Voltage Protection

Internal Thermal Protection

TSSOP-28 EP Package

The MP7752 utilizes a stereo BTL structure

capable of delivering 15W per channel into 8Ω

speakers with a 16V power supply. MPS

class-D audio amplifiers exhibit the high fidelity

of class-AB amplifiers at high efficiency.

The MP7752 includes an internal circuit which

allows the system to shut down automatically

after the absence of the audio signal is detected.

This feature is used for energy-using products

and battery operated applications.

Adjustable Power Limiter

Automatic Shutdown with Zero Input Signal

Detection



Fault Output Flag

Also, it has an adjustable power limit function.

The PLIMIT circuit sets a limit on the output

peak-to-peak voltage. This is done by limiting

the duty cycle to a fixed maximum value. This

limit can be thought of as a "virtual" voltage rail,

which is lower than the supply connected to

PVCC.

APPLICATIONS



DVD Receiver

Active Speaker
