General Description

SFL669 is a high precision AC/DC offline PSR (Primary Side Regulation) power switch for LED luminaries.

The IC can provide very tight (less than 3%) constant current control (CC) ideal for LED lighting applic

Key Features

  • Built-in 600V Power MOSFET.
  • Primary Side Regulation (PSR) Control, No Secondary Feedback Circuit Required.
  • 1% Precision (@Tj=25 ℃) Internal Reference Voltage for Constant Current (CC) Control.
  • Wide VDD Range (10 to 30V) Eases Flexible LED System Design.
  • Precision LED Output Voltage Clamp.
  • Compensate for Line Voltage Variation and Transformer Inductance Tolerance.
  • Built-in Soft Start.
  • All Pins Floating Protection.
  • LED Open/Short Circuit Protection.
