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