About This Product

■Summary

The MP7758 is an inductorless, analog input, Class D audio amplifier that drives stereo speakers in a bridge-connected load configuration. This device is a fully integrated audio amplifier, significantly reducing the size of your solution. Integrated 240mΩ power MOSFET and short circuit protection circuit. The MP7758 features startup/shutdown pop noise rejection and advanced EMI performance. This device can pass EMC tests without an inductor. The device utilizes a BTL construction capable of delivering 15W per channel to an 8Ω speaker with a 16V power supply. MPS' Class D audio amplifiers exhibit the high fidelity and high efficiency of Class AB amplifiers. The MP7758 includes internal circuitry that can automatically shut down the system after detecting the absence of an audio signal. This feature is ideal for energy-using products and battery-powered applications. This device provides adjustable power limit (PLIMIT) functionality. 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 acts as a virtual voltage rail and is lower than the power supply connected to PVCC. The MP7758 is offered in a TSSOP-28 EP package.

■Features and benefits

・Operation from 5V to 18V with a single power supply ・±5A peak current output ・Output power: 9.5W/channel at 12V, 8Ω load, 10%THD ・15W/channel at 16V, 8Ω load, 10% THD ・90% efficiency with 8Ω load, 10% THD, 1kHz, 12V supply voltage ・240mΩ power MOSFET ・Pop removal at startup/shutdown ・Short circuit protection circuit ・Inductor topology ・Advanced EMI performance ・Current limit for all switches ・Internal low voltage protection (UVP) ・Internal thermal protection ・Adjustable power limit ・Automatic shutdown by zero input signal detection ・Failure output flag ・Provided in TSSOP-28EP package
