The NCL30167 is a high PF CrM Boost Controller relying on an external FET for offline LED drivers optimized for new medium power HV LEDs. The Cascoded FET approach allows the use of an off-the-shelf inductor for better bill-of-material. It supports leading and trailing edge dimmers and the dimming curve complies with NEMA SSL6/7A
