Product Overview:

The NCL30186DDR2G is an AC-DC power factor corrected flyback controller for isolated and non-isolated ‘intelligently dimmable’ constant current LED drivers. The controller operates in a quasi-resonant mode for optimal efficiency, and the NCL30186DDR2G is particularly well suited for very compact, space-efficient designs, supporting both analogue and PWM dimming via dedicated dimming inputs for controlling the average LED current.
