Power Supply Circuit Example
The figures below show an example of a circuit used to generate LCD drive power supply voltages V0 to
V8. In this example, 18 levels of voltage are generated by divided resistance to alternate the current for
the LCD panel, and either positive or negative voltages are selected and supplied to the HD66330T. To
stabilize voltage, an operational amplifier should be connected to each selector output.

Maximum
±
10 mA direct current
(maximum
±
5 mA for each of the L- and
R-pins) flows in the LCD drive power
supply voltage pins V0 to V8 of one
HD66330T. When 10 ICs are used, the
current amounts to
±
100 mA maximum.
The direct current changes within 0 to
±
100 mA depending on the display data.
The LCD drive power supply circuit must
be able to provide stable voltage despite
the change in the current input to the IC.
The following shows a circuit example:
