Overview

SY5800 Single Stage Flyback And PFC Controller With Primary Side Control For LED Lighting Preliminary datasheet.

Key Features

  • Primary side control eliminate the opto-coupler.
  • Internal high current MOSFET driver: 1A sourcing and 2A sinking.
  • Low quiescent current at start up mode: 10uA typical.
  • 16V rising UVLO with 9V hysteresis.
  • Valley turn-on of the primary MOSFET to achieve low switching loss.
  • 0.5V max sense voltage on the primary side to minimize the conduction loss.
  • Reliable short LED and Open LED protection.
  • Good power factor(>0.90) with sin.
