AAT3190 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...
