12V to 30V high power 2x100W dual channel Class D audio amplifier boost combination solution

[Introduction]At present, trolley speakers or car audio systems use 12V lead-acid batteries as the main power supply. Due to the limitation of voltage, it is difficult to substantially improve the output power of speakers. The power of more than 50W is mainly used in the market at this stage. The boost audio solution of boost + TPA3116 is mainly used in the market. Because the maximum working voltage of TPA3116 is 26V, considering the reliability, it can be boosted to 24V, and the output is 4 Euro 65W (THD1%).
