The output voltage of the integrated boost converter may be adjusted by a resistive feedback divider between the boost output voltage (VBST) and the feedback pin (FB). The boost voltage must be programmed to a value greater than the maximum peak signal voltage that the user expects to create with the device amplifier. Lower boost voltages achieve better system efficiency when lower amplitude signals are applied, thus the user must take care not to use a higher boost voltage than necessary. The maximum allowed boost voltage is 105 V.
