Notes: 1.

Boosting output voltage should not exceed the power supply voltage (2) (13V max.)
in the absolute maximum ratings. Especially, voltage of over 4.3V should not be input
to the reference voltage (Vci) when boosting three times.
Vci input terminal is used for reference voltage and power supply for the internal booster.
Input current into the Vci pin needs three times or more of load current through the
bleeder resistor for LCD. So, when it adjusts LCD driving voltage (Vlcd), input voltage
should be controlled with transistor to supply LCD load current.
Please notice connection (+/–) when it uses capacitors with poler.
