LM3463 Overview
The LM3463 is a six channel linear LED driver with Dynamic Headroom Control (DHC) interface that is specialized for high power LED lighting applications. The variation of the output current of every output channel in the temperature range of -40°C to 125°C is well controlled to less than ±1%. The output current of every channel is accurately matched to each other with less than ± 1% difference as well.
