Product Summary
The AAT1164C-Q5-T is a triple-channel TFT LCD power solution. The AAT1164C-Q5-T 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 AAT1164C-Q5-T 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.
