25~29 V4~V0
O
DC/DC voltage converter. Connect a capacitor between this terminal and
the CAP2P terminal.
O
DC/DC voltage converter. Connect a capacitor between this terminal and
the CAP2N terminal.
LCD driver supplies voltages.
P Voltages should be according to the following relationship:
V0V1V2V3V4VSS.
Output voltage regulator terminal. Provides the voltage between VSS
andV0 through a resistive voltage divider.
30 VR I IRS =L: the V0 voltage regulator internal resistors are not used.
IRS =H: the V0 voltage regulator internal resistors are used.

This is the power control terminal for the power supply circuit for liquid
crystal drive.
33 HPM I /HPM = H: Normal mode
/HPM = L: High power mode (suggested)
This terminal selects the resistors for the V0 voltage level adjustment.
IRS =H: Use the internal resistors
34 IRS I IRS =L: Do not use the internal resistors. The V0 voltage level is
regulated by an external resistive voltage divider attached to the VR
terminal
35 ESD_2 - Electrostatic Discharge.
1 A P LED backlight power supply (+).
2 K P LED backlight power supply (-).
