LM3466 Overview
Key Specifications
Package: TO-220-7
Mount Type: Through Hole
Pins: 7
Max Voltage (typical range): 70 V
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.
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 Active LED Strings
