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), CCD Sensors and OLEDs. Two low-power charge pumps convert input supply voltages ranging from 2.7-5.5V into two independent output voltages.

FEATUREs
• VIN Range: 2.7-5.5 Volts
• Adjustable ± dual charge pump
• Positive supply output up to +25V
• Negative supply output down to -25V
• Up to 30mA output current
• 1.0 MHz Switching Frequency
• < 1.0µA Shutdown Current
• Internal power MOSFETs
• Internally controlled Soft-Start
• Fast Transient Response
• Ultra-Thin Solution (No Inductors)
• -40°C to 85°C Temperature Range
• Available in 8-Pin MSOP, 12-pin TSOPJW

APPLICATIONs
• TFT Active-Matrix LCDs
• Passive-Matrix Displays
• Personal Digital Assistants (PDAs)
• CCD Sensor Voltage Bias
• Organic LEDs (OLED)
