Direct PWM input dimming
operation can be realized by
inputting a suitable dimming pulse
train to the DIM pin. The LX27901
supports analog LED current control
utilizing the BRTA pin for setting the
analog LED current.
In addition, a proprietary dimming
algorithm ACU_BRITE® is
incorporated. The controller
integrates the pulsed LED current
and compares it with a reference for
very accurate brightness control
irrespective of duty cycle.
