5.2 Voltage Converter
power supply voltage VI to four times (triple or double) using clocks from the clock generator. However, the
3rd or double boosting output cannot be obtained simultaneously with for the quadruple boosting. Fig.5.2 shows
the potential relations at quadruple (3rd or double) boosting.
IC so that the cable is as short as possible.

The voltage converter, which consists of boosting control circuit and voltage converter, boosts the input
In the parallel connection, the C2P pin is used as a clock output pin in the master side (see Fig.9.8).
[Notes on connecting the capacitor for voltage conversion]
When connecting the capacitor to the C1P, C2P, C1N, C2N, C3N, and VO pins, place the capacitor near this
