Product Overviews Of TPA3128D2DAPR

TPA3128D2DAPR is 2x30W Class-D Amplifier With Low Idle Power Dissipation. TPA3128D2DAPR 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 TPA3128D2DAPR allows it to do 2 × 30W without external heat sink on a dual layer PCB.

TPA3128D2DAPR proposed an efficiency boost Mode, which can dynamically reduced the current ripple of the external LC filter and the idle current .

TPA3128D2DAPR 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.

TPA3128D2DAPR is 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.
