GENERAL DESCRIPTION

The AAT1164/AAT1164B/AAT1164C is a triple-channel

TFT LCD power solution that provides a step-up PWM

controller, two high voltage LDO drivers (one for positive

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,

internal soft-start circuit. The thermal and power fault

protection prevents internal circuit being damaged by

excessive power.

The high voltage LDO drivers generate two regulated

output voltage (V

dividers. VGH voltage does not activate until DLY voltage

exceeds 1.25V.

The

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

gamma corrections and VO3 is for V

circuit condition, operational amplifiers are capable of

sourcing ±100mA current for V

current for V

With the minimal external components, the

AAT1164/AAT1164B/AAT1164C offers a simple and

economical solution for TFT LCD power.
