AC-DC Power Factor Corrected LED Driver
The NCL30186 is an AC-DC power factor corrected flyback controller targeting isolated and non−isolated “Smart−dimmable” constant current LED drivers. The controller operates in a quasi−resonant mode to provide optimal efficiency. The current control algorithm supports flyback, buck−boost, and SEPIC topologies.
