ANX6923 Description
The ANX6923 is a highly pact white LED driver especially optimized for thin-film transistor (TFT) liquid crystal displays (LCDs) backlight. The chip can drive up to six strings of LEDs and up to ten LEDs in series per string. Wide input voltage range from 2.7V to 24V makes ANX6923 well suited for applications ranging from a one-cell lithium-ion battery tablet PC to a full-size notebook PC.
