Constant current regulator.
Boost topology (step up converter), must always have a load connected.
Dimming capability via external potentiometer.
Onboard trimpot to set maximum output current.
0.80" diameter board, single sided components. 0.26" maximum thickness.
High efficiency (typically 90% or better).
2.7V - 12V input voltage (being a boost converter, input voltage must be less than output voltage).
3V - 16V output voltage.
Output current 1000mA (max), depends on input/output voltage differential.
Capable of driving 1 or 2 series connected Luxeon 5W LEDs or 2 to 4 series connected Luxeon 1W or Luxeon 3 LEDs.
