Boosted Class D Amplifiers

Does the typical output power reported in the Class D spec (e.g. TPA2025) based on the VBAT voltage or the Boosted Voltage?

    Hello Ricardo

    Welcome to E2E, thank you for your interest in our products.
    In this case, the output power is based on the VBAT voltage and L=2.2uH. You could refer the figure 25 of the amplifier's datasheet to find the used circuit to get the typical characteristics.
