ANAX ANX6623AAQ WQFN-16L, 3x3

DESCRIPTION
The ANX6623 is an integrated power supply
solution optimized for small to medium size thinfilm
transistor (TFT) liquid crystal displays
(LCD’s).
The boost converter operates at a fixed
frequency of 1.2MHz. The integrated N-channel
FET has a current limit of 1.8A.
The positive and negative charge pumps provide
regulated TFT LCD gate-on and gate-off
supplies. Both outputs can be adjusted by
external resistive voltage dividers.
The integrated operational amplifier is typically
used for LCD VCOM driving; the output can sink
or source up to 150mA short-circuit current.
A built-in voltage detector generates a reset
signal when the input voltage drops below 2.6V.
The reset signal is active low and has a 123ms
blanking time during power-on.
The ANX6623 is available in a thin 16-pin 3x3
mm WQFN green package.
