Keywords:buck regulator  high-brightness LED  LED  HBLED  Luxeun K2 Emitter 

The LM3404/04HV is a buck regulator derived controlled current source designed to drive a series string of high power, high-brightness LEDs (HBLEDs) such as the Luxeon K2 Emitter at forward currents of up to 1A. The board can accept an input voltage ranging from 6V to 42V when using the LM3404. When using the pin-for-pin compatible LM3404HV the upper bound of input voltage is 75V. The converter output voltage adjusts as needed to maintain a constant current through the LED array.
