onsemi NCP1652
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.| Part No. | NCP1652 |
