com Positive LDO Driver GENERAL DESCRIPTION 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 amplifier, current sense circuit, comparator, under-voltage lockout protection and internal soft-start circuit.
The thermal and power fault protection prevents internal circuit being damaged by excessive power.
The LDO drivers generate two regulated output voltage set by external resistor divide...
