Description
OB3306 is a high integrated and
high performance Cold Cathode
Fluorescent Lamp (CCFL) controller optimized for LCD monitor
backlight application. It integrates
high precision (2%) 4 channels of
current and 1 channel of voltage
feedback control, and thus
provides a low-cost and high
reliability LCD backlight solution
with minimum system BOM count.
