9.5 3rd Boosting
voltage in the VO pin.
S1F76540M0C Series Technical Manual (Rev.1.0)
Run only the booster, perform 3rd boosting in the negative direction for input voltage VI, and generate the
In this case, the regulator is not used, so the voltage containing ripple components is generated in the VO pin.
Fig.9.6 shows a connection example.
