Description: NCL30185 Power Factor Corrected Quasi- Resonant Primary Side Current-Mode Co ntroller for LED Lighting with Line St ep Dimming and www.onsemi.com Thermal Foldback The NCL30185 is a controller targeting isolated and non−isolated “smart−dimmable” constant−curre nt LED drivers. Designed to support fly back, buck−boost, and SEPIC topologie s, its proprietary current−control al gorithm provides near−unity power fac tor and 8 1 SOIC−8 NB CASE 751 tigh tly regulates a constant LED current fr om the primary side, thus eliminating t he need for a secondary−side feedback circuitry or an optocoupler. Housed in the SOIC8, the NCL30185 is specificall y intended for very compact space−efficient designs. The
