Example of Power-supply Voltage Generator for More Than Five-times Boosting Output
The HD66740 incorporates the booster for up to five-times boosting. However, the LCD drive voltage
(VLCD) will not be enough for five-times boosting from Vcc when the power-supply voltage of Vcc is
low or when the LCD drive voltage is high for the high-contrast LCD display. In this case, the reference
voltage (Vci) for boosting can be set higher than the power-supply voltage of Vcc.
Set the Vci input voltage for the booster to 3.6 V or less within the range of Vcc + 1.0 V. Control the
Vci voltage so that the boosting output voltage (VLOUT) should be less than the absolute maximum
ratings (17 V).
