The TPA3128D2 and TPA3129D2 have low idle power loss and 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 2 × 30 W without external heat sink on a dual layer PCB. The high efficiency of the TPA3129D2 device allows it to do 2 × 15 W without external heat sink on a dual layer PCB. This device proposed an efficiency boost Mode, which can dynamically reduced the current ripple of the external LC filter and the idle current .
The TPA31xxD2 advanced oscillator/PLL circuit employs a multiple switching frequency option to avoid AM interferences, which is achieved together with an option of either master or slave option, making it possible to synchronize multiple devices.
The TPA31xxD2 devices are fully protected against faults with short-circuit protection and thermal protection as well as overvoltage, undervoltage, and DC protection. Faults are reported back to the processor to prevent devices from being damaged during overload conditions.
