Product Summary
The LM3464MH is a 4-channel high voltage current regulator that provides a simple solution for LED lighting applications. The LM3464MH 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. The applications of the LM3464MH are Streetlights, Solid State Lighting Solutions. Protection features include VIN under-voltage lock-out, LED open/short circuit and over-temperature fault signaling to the system controller.
