onsemi NCL30185
The NCL30185 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 8 1 SOIC−8 NB CASE 751 tightly regulates a constant LED current from the primary side, thus eliminating the need for a secondary−side feedback circuitry or an optocoupler. The device is highly integrated MARKING DIAGRAM 8 L30185x ALYW G with a minimum number of external components.| Part No. | NCL30185 |
