SF5922 - High Precision Primary Side Regulation (PSR) CV/CC Power Switch

Description

SF5922 is a high performance, highly integrated DCM (Discontinuous Conduction Mode) Primary Side Regulation (PSR) power switch for offline small power converter applications.

SF5922 uses Pulse Frequency Modulation (PFM) control to improve efficiency and eases system EMI design.

Features

  • Built-in 600V Power MOSFET.
  • Low Standby Power Under 30mW, Easily to Pass Energy Star EPS2.0.
  • Primary Side Regulation (PSR) without TL431 and Opto-Coupler.
  • ± 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.
  • Built-in Control Loop Compensation in CV Mode.
  • All Pins Floating Pr.
