The amplifier based on the class H from Philips audio amplifier IC, it can deliver 36W RMS and 70W power music, all from the supply voltage of 13.8V. This amplifier can provide 36W RMS continuous into 4 ohm load when using a 13.8Vsupply.
However, it is able to deliver 70W output power signal (music) in the dynamic condition. As we can see from the drawings and schematic diagrams, this powerful amplifier uses only few part.
