Note (1) The Dimming signal should be valid before backlight turns on by BLON signal. It is inhibited to
change the internal/external PWM signal during backlight turn on period.
Note (2) The power sequence and control signal timing are shown in the following figure. For a certain
reason, the converter has a possibility to be damaged with wrong power sequence and control
signal timing.
Note (3) While system is turned ON or OFF, the power sequences must follow as below descriptions:
Turn ON sequence: VBL → PWM signal → BLON
Turn OFF sequence: BLOFF → PWM signal → VBL
Note (4) When converter protective function is triggered, ERR will output open collector status.
