General Description

The AAT3190 charge pump controller provides the regulated positive and negative voltage biases required by active matrix thin-film transistor (TFT) liquid-crystal displays (LCDs), charge-coupled device (CCD) sensors, and organic light emitting diodes (OLEDs).

Two low-power charge pumps convert input supply voltages ranging from 2.7V to 5.5V into two independent output voltages.

The dual low-power charge pumps independently regulate a positive (VPOS) and negative (VNEG) output voltage.
