TPA3156D2 Overview
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.
