Note 3. Output power is measured directly at the output pins of the IC.
Note 4. With bootstrap and a 100kΩ resistor from Pin12 to the positive supply voltage (VP), value
of the bootstrap capacitor is 47µF.
Note 5. Frequency response externally fixed.
Note 6. Ripple rejection measured at the output with a source impedance of 0Ω (maximum ripple
amplitude of 2V) and a frequency between 1kHz and 10kHz.
