Especificações Técnicas

TEXAS INSTRUMENTS TPA3128D2/TPA3129D2 CLASS-D AMPLIFIERS HAVE LOW IDLE POWER LOSS. THIS FEATURE HELPS TO EXTEND THE BATTERY LIFE OF BLUETOOTH/WIRELESS SPEAKERS AND OTHER BATTERY-POWERED AUDIO SYSTEMS. THE HIGH EFFICIENCY OF THE TPA3128D2 DEVICE ALLOWS IT TO DO 2X 30W WITHOUT EXTERNAL HEAT SINK ON A DUAL LAYER PCB. THE HIGH EFFICIENCY OF THE TPA3129D2 DEVICE ALLOWS IT TO DO 2X 15W WITHOUT EXTERNAL HEAT SINK ON A DUAL LAYER PCB. EACH DEVICE INCLUDES AN EFFICIENCY BOOST MODE, WHICH CAN DYNAMICALLY REDUCE THE CURRENT RIPPLE OF THE EXTERNAL LC FILTER AND THE IDLE CURRENT. THE TPA3128D2/TPA3129D2 ADVANCED OSCILLATOR/PLL CIRCUIT EMPLOYS A MULTIPLE SWITCHING FREQUENCY OPTION.   THIS OPTION ALLOWS THE DEVICE TO AVOID AM INTERFERENCES, WHICH IS ACHIEVED TOGETHER WITH AN OPTION OF EITHER MASTER OR SLAVE OPTION MAKING IT POSSIBLE TO SYNCHRONIZE MULTIPLE DEVICES. FEATURES SUPPORTS MULTIPLE OUTPUT CONFIGURATIONS 2×30W INTO A 8- BTL LOAD AT 24V (TPA3128D2) 2×15W INTO A 8- BTL LOAD AT 15V (TPA3129D2) WIDE VOLTAGE RANGE: 4.5V TO 26V EFFICIENT CLASS-D OPERATION VERY LOW IDLE CURRENT: GREATER THAN 90% POWER EFFICIENCY COMBINED WITH LOW IDLE LOSS GREATLY ELIMINATES NEED FOR HEAT SINK ADAPTIVE MODULATION SCHEMES BASED ON OUTPUT POWER SMART AMPLIFIER DRIVERS TO REDUCE THE REQUIREMENT FOR RC SNUBBERS MULTIPLE SWITCHING FREQUENCIES AM AVOIDANCE MASTER AND SLAVE SYNCHRONIZATION 300KHZ TO 1.2MHZ SWITCHING FREQUENCY FEEDBACK POWER-STAGE ARCHITECTURE WITH HIGH PSRR REDUCES PSU REQUIREMENTS PROGRAMMABLE POWER LIMIT PARALLEL BTL MODE AND MONO-CHANNEL MODE SUPPORT SUPPORTS BOTH SINGLE AND DUAL POWER SUPPLY MODES INTEGRATED SELF-PROTECTION CIRCUITS INCLUDING OVERVOLTAGE, UNDERVOLTAGE, OVERTEMPERATURE, DC-DETECT, AND SHORT CIRCUIT WITH ERROR REPORTING THERMALLY ENHANCED PACKAGES DAP (32-PIN HTSSOP PAD DOWN FOR TPA3128D2 AND TPA3129D2) APPLICATIONS BLUETOOTH/WIRELESS SPEAKERS SOUNDBARS MINI-MICRO COMPONENT, DOCKS LCD-LED TVS HOME THEATERS TPA3128D2 CLASS-D AMPLIFIER WITH LOW IDLE POWER DISSIPATION MAIORES DETALHES DE TPA3128D2 NO SITE DO FABRICANTE: HTTPS://WWW.TI.COM/LIT/DS/SYMLINK/TPA3128D2.PDF?TS=1654260914679&REF_URL=HTTPS%2 TAGS DE TPA3128D2: TPA3129D2, TPA3128, TPA3128D2, CI DE AUDIO CHARGE4, CI AUDIO CHARGE4, JBL CHARGE4 CI DE AUDIO, JBL CHAGE 4 CI DE AUDIO, CI DE AUDIO JBL CHARGE 4, 3128D2
