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, under-voltage lockout protection and
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 (VOUT2 and VOUT3) set by external resistor
dividers. VGH voltage does not activate until DLY voltage
exceeds 1.25V.
The AAT1164/AAT1164B/AAT1164C contains 4+1
operational amplifiers. VO1, VO2, VO4, and VO5 are for
gamma corrections and VO3 is for VCOM. In the short
circuit condition, operational amplifiers are capable of
sourcing ±100mA current for VGAMMA, and ±200mA
current for VCOM.
With the minimal external components, the
AAT1164/AAT1164B/AAT1164C offers a simple and
economical solution for TFT LCD power.
