NCL30001 High-Efficiency Single Stage Power Factor Correction and Step-Down Offline LED Driver The NCL30001 is a highly integrated controller for implementing power factor correction (PFC) and isolated step down ac−dc power conversion in a single stage, resulting in a lower cost and reduced part count solution. This controller is ideal for LED Driver power supplies with power requirements between 40 W and 150 W. The single stage is based on the flyback converter and it is designed to operate in continuous conduction (CCM). The NCL30001 can be configured as as constant current driver or a fixed output driver for two stage LED lighting applications. In addition, the controller features a proprietary Soft−Skip™ to reduce acoustic noise at light loads.
