Notes:1. The reference voltage input (Vci) must be adjusted so that the output voltage after boosting will not exceed
the absolute maximum rating for the liquid-crystal power supply voltage (17 V). Particularly, Vci must be
3.3 V or less for five-times boosting.
2. Vci is both a reference voltage and power supply for the booster; connect it to Vcc directly or combine it
with a transistor so that sufficient current can be obtained.
3. Polarized capacitors must be connected correctly.
4. Circuits for temperature compensation should be based on the sample circuit in figure 24.
