SF5920 Datasheet (SiFirst) - CV/CC Controller

SF5920, CV/CC Controller

SF5920 is a high performance, highly integrated DCM (Discontinuous Conduction Mode) Primary Side Regulation (PSR) controller for offline small power converter applications.

SF5920 uses Pulse Frequency Modulation (PFM) control to improve efficiency and eases system EMI design.

The IC dramatically low
