LM3464 Datasheet (National Semiconductor)

LM3464, LED Driver

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 Nchannel MOSFETs and sense resistors to give accurate driving current
