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.
