GENERAL DESCRIPTION OZ9906
The OZ9906 is a high effi ciency switch-mode DC/DC controller that drives up to 6
LED strings connected in parallel. It is targeted for large-size monitor and TV applica-
tions.
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 function-
ing in the event that any string(s) is damaged during normal operation.
