SF5926

SF5920 : 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 lowers system cost by eliminating the opto-coupler and secondary control circuits. It also can provide very tight output voltage regulation (CV), in addition to output current control (CC) ideal for charging applications. SF5920 has built-in proprietary NC-Cap/PSRTM control for CV control, which eliminates external compensation or filtering capacitor. It also has built-in proprietary cable drop compe.
