Datasheet Summary
NCP1652, NCP1652A High-Efficiency Single Stage Power Factor Correction and Step-Down Controller
The NCP1652 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 notebook adapters, battery chargers and other off- line applications with power requirements between 75 W and 150 W. The single stage is based on the flyback converter and it is designed to operate in continuous conduction (CCM) or discontinuous conduction (DCM) modes. The NCP1652 increases the system efficiency by incorporating a secondary driver with...
