30W, stereo, Class-D audio amplifier with SpeakerGuard 'TPA3128D2'
The TPA3128D2 device is a high-efficiency stereo digital amplifier power stage that can drive speakers up to 60W/2Ω in PBTL mode. It has low idle power loss, which can extend the battery life of Bluetooth/wireless speakers and other battery-powered audio systems. Additionally, due to its high efficiency, it can output 2×30W without an external heat sink on a dual-layer PCB. Furthermore, it is equipped with short-circuit protection, thermal protection, and over-voltage, under-voltage, and DC protection, providing complete protection against faults. Faults are reported back to the processor, preventing damage to the device in overload situations. 【Features】 ■ Supports multiple output configurations ■ Wide voltage range: 4.5V to 26V ■ Efficient Class-D operation ■ Multiple switching frequencies ■ High PSRR feedback power stage architecture reduces PSU requirements ■ Programmable power limit *For more details, please contact us.
