PWM grayscale control
satiety region of the constant current characteristic. When using this IC outside the saturation area, PWM grayscale
control cannot be normally done.
Switching to Open Circuit Detection (OOD) and Short Circuit Detection (OSD) Modes
This IC is possible to PWM grayscale control by the input of the PWM signal to the EN terminal.
When PWM grayscale control is done, we recommend the LED power-supply voltage to be set to become the
Switching to OSD mode
