350mA MicroPuck LED Driver - With Leads

350mA MicroPuck LED Driver - With Leads
The 2009A MicroPuck is a 350mA driver specifically designed to power a single high power LED using 1 or 2 battery cells. (AAA, AA, D, etc.)

The MicroPuck provides maximum illumination to the LED while still mimicking the light drop-off of an incandescent bulb, which dims as the battery is depleted. Unlike an incandescent bulb, the driver's current consumption drops at very low voltages, allowing usable light from the LED for much longer than conventional flashlights. Battery recovery (after the flashlight has been turned off) is also improved.

Additional Information

While this driver is designed to drive a single high power LED from one or two battery cells, it can also be configured to operate in a number of other opeating modes, including:
  • Buck Driver - 3.7 to 8 VDC input voltage
  • Buck/Boost Driver - 1 to 7 VDC input voltage
  • In Parallel as a Boost Driver - Up to 800mA of drive current
  • In Parallel as a Buck/Boost Driver - 1 to 7 VDC input voltage with up to 700mA of drive current

For more details and sample schematics see the Additional Applications Note.
