GENERAL DESCRIPTION

The OZ9906 is a high efficiency switch-mode DC/DC controller that drives up to

6 LED strings connected in parallel. It is targeted for large-size monitor and TV

applications.

OZ9906 provides six (6) LED current sense inputs. The IC provides individual

LED current regulation for each LED string. This allows the backlight to remain

functional in the event that any string (s) is damaged during normal operation.
