Description for the TPA3156D2

The TPA3156D2 has low idle power loss and helps to extend the battery life ofBluetooth/Wireless speakers and other battery-powered audio systems. The high efficiency of theTPA3156D2 device allows it to do 2 × 70 W with external heat sink on a dual layer PCB. This deviceintegrates an efficiency boost mode, which dynamically reduces the current ripple of the externalLC filter and the idle current .

The TPA3156D2 advanced oscillator/PLL circuit employs a multiple switching frequencyoption to avoid AM interferences, which is achieved together with an option of either master orslave option, making it possible to synchronize multiple devices.

The TPA3156D2 devices are fully protected against faults with short-circuit protectionand thermal protection as well as overvoltage, undervoltage, and DC protection. Faults are reportedback to the processor to prevent devices from being damaged during overload conditions.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships  tube or tray  devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
