AAT11671 Datasheet Integrated Tft Lcd Power Solution

Manufacturer: Advanced Analog Technology

Overview: Advanced Analog Technology, Inc. Product information presented is current as of publication date. Details are subject to change without notice.

General Description

The AAT11671 provides a step-up PWM controller, negative high voltage LDO drivers, low dropout linear regulator, V operational amplifier and one high voltage switch (up to 28V) for TFT LCD display.

RST pin will issue a reset signal to T when VDD voltage is too low.

The PWM controller consists of an on-chip voltage reference, oscillator, error amplifier, current sense circuit, parator, under-voltage lockout protection and soft-start control circuit.
