The TPA3128D2 devices are stereo efficient, digital amplifier power stage for driving
speakers up to 60 W / 2 Ω in PBTL mode. The TPA3128D2 has 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. This device proposed an efficiency boost Mode, which can dynamically reduced the current
ripple of the external LC filter and the idle current.
The TPA3128D2 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 TPA3128D2 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.
