产品概述
The TPA3156D2 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
TPA3156D2 device allows it to do 2 × 70 W with external heat sink on a dual layer PCB. This device
integrates an efficiency boost mode, which dynamically reduces the current ripple of the external
LC filter and the idle current .The TPA3156D2 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 TPA3156D2 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.
