AAT11671 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...
