FAN7311B Datasheet, PDF (9/14 Pages) Fairchild Semiconductor – LCD Backlight Inverter Drive IC

Timing Diagram
The FAN7311B uses the improved phase-shift control full-bridge to drive CCFL. As a result, the temperature difference
between the left and the right leg is almost zero. The detail timing is shown below.
