GENERAL DESCRIPTION OZ9961
The OZ9961 is a LED controller that drives up to six (6) strings of LEDs in parallel
confi guration, with multiple LEDs per string connected in series. It provides six (6)
LED current sense inputs in an “OR” confi guration to improve backlight reliability.
This allows the backlight to remain functioning in the event that any string (s) is dam-
aged during normal operation.
OZ9961 supports either analog, external Pulse Width Modulation (PWM) or internal
Low frequency PWM (LPWM) dimming control.
