The NCL30186SMRTGEVB Evaluation Board 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. Thanks to a novel control method, the device is able to tightly regulate a constant LED current from the primary side.
