SD6857TR
Overview
SD6857 is the primary side controlled LED controller with PFC. It adopts PFM technology for providing accurate constant current control with high average efficiency.
- 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
