Summary

The built-in Asynchronous Automatic boost module provides abundant power output to the speaker, and the maximum boost value can be selected between 5.7V, 6.6V, 7.2V and 7.5V. When the input signal is small, the boost circuit does not work, class D is directly supplied by the power supply; when the input signal becomes larger, the boost module is automatically turned on to boost the intermediate level to supply power to class D; when the input signal becomes larger, the boost circuit continues to boost to the maximum voltage set by the user to supply power to class D, which can improve the efficiency of the system and prolong the battery life. With AGC anti-breaking sound 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 of SC2306 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. In addition, built-in overcurrent protection, short circuit protection and overheat protection can effectively protect the chip from damage under abnormal working conditions.
