AAT1168 - Advanced Analog Technology

AAT1168 TRIPLE-CHANNEL TFT LCD POWER SOLUTION

The AAT1168/AAT1168A/AAT1168B is a triple-channel TFT LCD power solution that provides a step-up PWM controller, two LDO drivers (one for positive high voltage and one for negative voltage), five operational amplifiers, and one high voltage switch up to 28V for TFT LCD display. The PWM controller consists of an on-chip voltage reference, oscillator, error am.
