DESCRIPTION
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 shortcircuit
protection circuits.
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.
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.
The MP7758 is available in a TSSOP-28 EP
package.
