Notes: 1. The reference voltage input (Vci) must be adjusted so that the output voltage after boosting will not exceed
the absolute maximum rating of the liquid-crystal power supply voltage (15V). Particularly, Vci must be
5V or less for triple boosting.
2. Vci is both a reference voltage and power supply for the booster; connect it to V
CC
directly or combine it with
a transistor so that sufficient current can be obtained.
3. Vci must be smaller than V
CC
.
4. To operate the voltage-follower correctly, potential differences between V
CC
and V1 and between V5 and
V
EE
must be 0.4V or greater, particularly for low-duty drive such as 1-line display.
5. Polarized capacitors must be connected correclty.
6. Circuits for temperature compensation should be designed based on the sample circuit shown in figure 35.
7. The HD66727's internal operational amplifiers have a reduced drive current to save current consumption;
when the internal operational amplifiers cannot fully drive the LCD panel used, an appropriate capacitor must
be inserted between each output of V1OUT to V5OUT and V
CC
to stabilize the operational amplifier output
(Figure 36).
