Summary

The SC2310 with built-in Asynchronous Automatic boost module provides ample power output to the speaker, and the maximum boost value can be selected between 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 voltage to the intermediate level of 5.7V to supply power to class D; when the input signal becomes larger, the boost circuit continues to boost until the user sets the maximum voltage to supply power to class D, which can improve the system. Work efficiency, prolong battery life.AGC with two optional modes can significantly improve the sound quality, create comfortable listening enjoyment, and protect speakers 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, effectively protect the chip from damage under abnormal working conditions.
