3 Description
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.
