The AAT1160 is a step up current mode PWM
converter that provides a one-channel step-up PWM
controller, four Gamma buffers, and one
COM
V
buffer. Internal soft-start function can efficiently
prevent inrush current when the power is on.
This PWM controller consists of an on-chip voltage
reference, error amplifier, current sense, pulse width
modulation
controller,
under-voltage
lockout
protection, thermal detect, soft-start, and fault
protection circuits.
The AAT1160 contains 4+1 operational amplifiers:
GO1, GO2, GO3, and GO4 for gamma corrections
and COUT for
COM
V
.
COM
V
and
GAMMA
V
are designed to increase
driving capability for thin film transistor liquid
crystal display (TFT LCD). Each buffer is capable
of driving heavy load and offering fast current

With minimal external components, the AAT1160
offers a simple and economical power management
solution for TFT LCD panels.
