SD6857 - PRIMARY SIDE CONTROLLED LED CONTROLLER

Description

SD6857 is the primary side controlled LED controller with PFC.

It adopts PFM technology for providing accurate constant current control with high average efficiency.

With SD6857, opto-couple, secondary feedback control, loop compensation circuit can be eliminated for reducing cost.

Features

  • Active power factor correction (APFC).
  • PSR CC/CV.
  • Ultra-low start-up current.
  • Primary side control.
  • Leading edge blanking.
  • Pulse-Frequency Modulation(PFM).
  • VCC overvoltage/undervoltage protection.
  • LED open/short circuit protection.
  • Internal over temperature protection.
  • Cycle by cycle current limiting.
  • Open loop protection.
  • Peak current compensation SOP-8-225-1.27.
