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.

OB3306 controls push pull topology and supports various dimming

functions and comprehensive

protections.
