LM3464 Description
The LM3464/64A is a 4-channel high voltage current regulator that provides a simple solution for LED lighting applications. The LM3464/64A provides four individual current regulator channels and works in conjunction with external N-channel MOSFETs and sense resistors to give accurate driving current for every LED string. Additionally, the Dynamic Headroom Control (DHC) output can be interfaced to the external power...
