NCL30086BHDR2G

LED照明驱动器 LED LIGHTING CONTROLLER

The NCL30086BHDR2G NCL30086BH is a controller targeting isolated and  non−isolated “smart−dimmable” constant−current LED drivers.  Designed to support flyback, buck−boost, and SEPIC topologies, its  proprietary current−control algorithm provides near−unity power  factor and tightly regulates a constant LED current from the primary  side, thus eliminating the need for a secondary−side feedback circuitry  or an optocoupler
