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 op.
