MP7758

18V, 2 x 15W Stereo BTL, Fixed-Frequency,

Inductorless Class-D Audio Amplifier

DESCRIPTION

FEATURES

The MP7758 is an inductorless, analog input

class-D audio amplifier that drives stereo

speakers in a bridge-tied load configuration.

The device is a fully integrated audio amplifier,

which reduces solution size dramatically. It

integrates 240mΩ power MOSFETs and short-

circuit protection circuits.



5V to 18V Operation from a Single Supply

±5A Peak Current Output

Output Power:

o 9.5W/Channel at 12V, 8Ω Load, 10%

THD

o 15W/Channel at 16V, 8Ω Load, 10%

THD



90% Efficiency with 8Ω Load, 10% THD,

1kHz, 12V Supply Voltage

240mΩ Power MOSFETs

Start-Up/Shutdown Pop Elimination

Short-Circuit Protection Circuits

Inductorless Topology

Advanced EMI Performance

All Switches Current Limited

Internal Under-Voltage Protection (UVP)

Internal Thermal Protection

Adjustable Power Limit

The MP7758 features start-up/shutdown pop

elimination, as well as advanced EMI

performance. The device can pass EMC tests

without an inductor.



The device 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, with high efficiency.

The MP7758 includes an internal circuit that

allows the system to automatically shut down

after the absence of an audio signal is detected.

This feature is well-suited for energy-using

products and battery-operated applications.

Automatic Shutdown with Zero Input Signal

Detection

Fault Output Flag



Available in a TSSOP-28 EP Package

The device offers an adjustable power limit

(PLIMIT) 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 functions as a virtual

voltage rail, and is lower than the supply

connected to PVCC.

APPLICATIONS



Wireless/Portable Speakers

TVs

DVD Receivers

Active Speakers
