TRIPLE-CHANNEL TFT LCD POWER SOLUTION

WITH OPERATIONAL AMPLIFIERS

FEATURES

ꢀ Built in 3A, 0.2Ω Switching NMOS

ꢀ Positive LDO Driver Up to 28V/5mA

ꢀ Negative LDO Driver Down to −14V/5mA

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.

ꢀ 28V High Voltage Switch for VGH

ꢀ Internal Soft-Start Function

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.

ꢀ 1.2MHz Fixed Switching Frequency

ꢀ 3 Channels Fault and Thermal Protection

ꢀ Low Dissipation Current

ꢀ QFN-32 Package Available

The LDO drivers generate two regulated output voltage

set by external resistor dividers. VGH voltage does not

activate until DLY voltage exceeds 1.25V.

PIN CONFIGURATION

The AAT1168/AAT1168A/AAT1168B contains 4+1

operational amplifiers. VO1, VO2, VO4, and VO5 are for
