543 power amplifier chip is a high-performance, low-power audio power amplifier solution, with high fidelity, low distortion, high output power characteristics. It features a new BTL architecture designed to deliver up to 35W of output power to 8Ω speakers for a wide range of audio applications. The chip also has built-in overheat protection, short-circuit protection, undervoltage protection and other protection functions, which can ensure the stability and safety of the system. At the same time, the chip can also achieve suspended computing, thereby reducing the number and cost of peripheral components.
