General Description
The
triple-channel pulse width modulation (PWM) solution
for the power supply of LCD displays. These devices
offer system engineers the flexibility to tailor-make the
power supply circuitry for specific applications. Each
channel contains its own error amplifier, PWM
comparator, dead–time control (DTC) and output driver.
The under-voltage protection, over voltage protection,
power sequence control, shutdown control circuit,
oscillator, short circuit protection, and voltage reference
circuits are the common features of the three channels.
The AAT1101 series contain two exclusive boost
circuits at CH1, CH3 and an exclusive buck_boost
circuit at CH2. AAT1101’s Power Up sequence initiates
at CH1 then CH2 and finally CH3. AAT1101A/C’s
Power Up sequence acts in the order of CH2, CH3, and
then CH1.
from CH2, CH1, and then CH3. At the completion of
the Power Up sequencing, the SCP pin stays low and
enters the Wait State of short circuit protection. Power
Up sequencing delay and short circuit protection delay
are set by connecting a capacitor to the SCP pin.
Furthermore, these devices can operate with supply
voltage ranging from 2.5V to 6.5V and function
efficiently in an environment with low power supply.
With a minimum number of external components, the
AAT1101 series offer a simple and cost effective
solution for TFT LCD.
