GENERAL DESCRIPTION OZ9908
The OZ9908 is a LED driver controller designed for large-screen LCD backlit by
LEDs. It provides an integrated eight channel LED current regulation control circuit.
Using external balance transistors for each channel, the IC is capable of driving a
current up to 350mA per LED channel.
OZ9908 provides individual Pulse Width Modulation (PWM) dimming for its respec-
tive LED string. The IC is suitable for LCD TV applications where area-lighting tech-
nology using local dimming control is applied.
