SF5920 - CV/CC Controller

Description

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.

Features

  • Low Standby Power Under 30mW, Easily to Pass Energy Star EPS2.0.
  • Proprietary NC-Cap/PSRTM (Primary Side Regulation) Control without External Compensation/Filtering Capacitor Needed.
  • ± 5% Constant Current (CC) and Constant Voltage (CV) Regulation at Universal AC Input.
  • Proprietary Cable Voltage Drop Compensation in CV Mode.
  • Compensate for Line Voltage Variation.
  • Compensate for Transformer Inductance Tolerances.
  • Pins Floating Protection.
  • PFM.
