Note 1. The circuit is DC adjusted at V_P = 6V to 18V and AC operating at V_P n= 8.5V to 18V.
Note 2. At 18V < V_P < 30V the DC output voltage ≤ V_P/2.

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 (V_P), 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.
