LM3402HVEVAL: 350mA @ Vin Max, 6 ~ 75V in
Summary
The LM3402HV circuit and BOM have been designed to provide a constant forward current of 350 mA to a single LED with a forward voltage of approximately 3.5V.
Ripple current will not exceed 70 mA peak-to-peak. Switching frequency for the demo board is 250 kHz ±10% over the input voltage range of 6V to 75V.
It can maintain regulated current through any number of LEDs as long as the combined forward voltage of the array does not exceed VO(MAX).
