9.6 Double Boosting
Run only the booster, perform double boosting in the negative direction for input voltage VI, and generate the
voltage in the VO pin.
In this case, the regulator is not used, so the voltage containing ripple components is generated in the VO pin.
Figure 9.7 shows a connection example.

Power-off method
Set the POFF2X pin to level LOW (VI); all circuits will be turned off.
About ripple voltage
For ripple voltage, see Section 9.4.
