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 5V to 18V Operation from a Single Supply class-D audio amplifier, which drives stereo 5A Peak Current Output speakers in bridge-tied-load configuration. It is Output Power: a fully integrated audio amplifier, which reduces 9.5W/Channel at 12V, 8 Load, 10%THD solution size dramatically. It integrates 240m 15W/Channel at 16V, 8 Load, 10%THD power MOSFETs and short-circuit protection 90% Efficiency with 8 Load, 10%THD, circuits, and it features start-up/shutdown pop 1kHz, 12V Supply Voltage elimination and advanced EMI performance. 240m Power MOSFETs Also, it is inductorless while passing the EMC Start-UP/Shutdown Pop Elimination test. Short-Circuit Protection Circuits Inductorless Topology The MP7752 utilizes a stereo BTL structure capable of delivering 15W per channel into 8 Advanced EMI performance speakers with a 16V power supply. MPS All Switches Current Limited class-D audio amplifiers exhibit the high fidelity Internal Under-Voltage Protection of class-AB amplifiers at high efficiency. Internal Thermal Protection TSSOP-28 EP Package The MP7752 includes an internal circuit which Adjustable Power Limiter allows the system to shut down automatically Automatic Shutdown with Zero Input Signal after the absence of the audio signal is detected. Detection This feature is used for energy-using products and battery operated applications. Fault Output Flag Also, it has an adjustable power limit function. APPLICATIONS The PLIMIT circuit sets a limit on the output TV peak-to-peak voltage. This is done by limiting DVD Receiver the duty cycle to a fixed maximum value. This Active Speaker limit can be thought of as avirtua voltage rail, which is lower than the supply connected to All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive.
