AAT11671 - Advanced Analog Technology

AAT11671 INTEGRATED TFT LCD POWER SOLUTION

The AAT11671 provides a step-up PWM controller, negative high voltage LDO drivers, low dropout linear regulator, VCOM operational amplifier and one high voltage switch (up to 28V) for TFT LCD display. RST pin will issue a reset signal to TCOM when VDD voltage is too low. The PWM controller consists of an on-chip voltage reference, oscillator, error amplifier.
