Summary

The built-in automatic boost module provides ample power output to the speaker, which can boost to 6.2V. When the input signal is small, the boost circuit does not work, Class D is directly powered by the power supply; when the input signal becomes larger, the automatic boost circuit starts, and Charge pump boosts to 6.2V voltage to supply Class D. This can improve the efficiency of the system and extend the battery life. With four modes of AGC anti-breaking function, it can significantly improve the sound quality, create comfortable listening enjoyment, and protect the loudspeaker from overload damage. With class AB/D mode switching function, switching to class AB can reduce the interference of power amplifier to FM in the system. The fully differential architecture effectively improves the chip's ability to suppress RF noise. PWM modulation structure without filter and built-in boost module reduce peripheral devices as much as possible. Built-in overcurrent protection, short circuit protection and overheat protection, effective protection chip in abnormal working conditions is not damaged.
