LM3466 Description
The LM3466 integrates a linear LED driver for lighting systems which consist of multiple LED strings powered by a constant current power supply. It balances the current provided by the supply in a preset ratio for each active LED string, where an active string is a fully turned on LED string, regardless of the number of strings connected to the supply or the forward voltage of each LED string. If any LED string...
LM3466 Key Features
- 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 Open (inactive) by Automatically Balancing the Current of Remaining Acti
- Works with a Constant Current Power Supply (ac/dc or dc/dc), and no munication to/from the Constant Current Power Supply
- Operates with Minimum Voltage Overhead to Maximize Power Efficiency
- Wide Input Voltage Range from 6 V to 70 V
- Fault Status Output
- Thermal Shutdown
