Product Summary

The AAT1164C-Q5-T 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 AAT1164C-Q5-T consists of an on-chip voltage reference, oscillator, error amplifier, current sense circuit, comparator, under-voltage lockout protection and internal soft-start circuit. The AAT1164C-Q5-T contains 4+1 operational amplifiers.
