SD6857TR - PRIMARY SIDE CONTROLLED LED CONTROLLER

Download the SD6857TR datasheet PDF. This datasheet also covers the SD6857 variant, as both devices belong to the same primary side controlled led controller family and are provided as variant models within a single manufacturer datasheet.

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.
