With the popularity of Bluetooth speakers and the improvement of users‘ requirements for sound quality and power, the mainstream audio power amplifiers in the market, such as 8002/8871/2018/ 5128, have been difficult to meet the requirements. Now, the built-in boost power amplifier launched by some domestic chip manufacturers is difficult to become the mainstream because of the price and cost. Shenzhen siyuante Technology Co., Ltd. is now vigorously promoting an esop-8 built-in non inductive charge pump boost 5W anti broken sound low-cost mono audio power amplifier ic-ZC8809. The esop-8 has a small package. The single charge pump architecture boost peripheral does not need inductance. The BOM cost of the overall PCBA of the speaker increases by about a few cents, and the power increases by two times, accelerating the popularization and application of the built-in boost power amplifier IC.
