LM3466 - Multi-String LED Balancer

Description

The LM3466 integrates a linear LED driver for lighting systems which consist of multiple LED strings powered by a constant current power supply.

Features

  • 1.
  • 2 Easy to Design for Lighting Systems Consisting of Multiple LED Strings (Supports Modular Design).
  • Automatically Balances the Current of Every Active LED String, even the Forward Voltage of Each String is Different.
  • Easy to Pre-Set and Fine-Tune Current Ratio Among LED Strings (e. g. , color temperature adjustment or CRI Enhancement).
  • ±1% Current Accuracy at Room Temperature and ±1.5% Over Temperature.
  • Maintains Constant Output Power if Some Strings.
