Output for panel drive
I/O
Range
Function
Charge-pump voltage or charge-pump reference voltage.
O
+2.5V
Power supply voltage for oscillator.
Please connect capacitor between VOUT0 and VSS.
Charge-pump voltage.
O
+5.0V
VOUT1 = VOUT0 × 2
Please connect capacitor between VOUT1 and VSS.
Charge-pump voltage.
O
+15.0V
VOUT2 = VOUT1 × 3
Please connect capacitor between VOUT2 and VSS.
Charge-pump voltage.
O
-15.0V
VOUT3 = VOUT2 × -1
Please connect capacitor between VOUT3 and VSS.
Capacitor connection pin for Charge-pump.
Please connect capacitor between corresponding CxyA and CxyB.
CxyA is positive connection pin for the flying capacitor.
-
CxyB is negative connection pin for the flying capacitor.
(With setting of 2.5V for the reference voltage, the capacitance
between terminals is not necessary between C01A and C01B.)
