Product Summary
The AAT1118/A/B is an adjustable triple-channel TFT LCD DC-DC converter that provides one current mode PWM, one positive charge pump and
one negative charge pump. Built-in functions include soft-start and power up sequencing. When power is turned on, soft-start avoids inrush current.
Power up sequencing feature provides compensation for LCD panel to maintain a smooth voltage during a turn-on cycle
