This 2-Cell 1W LED Drive module was designed to power (1) 1 Watt Luxeon®,
or strings of 5mm (T 1-3/4) LEDs efficiently and with stability. This driver has been
designed to provide maximum illumination to the LED while still mimicking
the light drop-off of an incandescent bulb, which dims as the batteries
are used up. Unlike an incandescent bulb, the driver's current consumption
drops at very low voltages, allowing usable light to be produced much
longer than conventional flashlights. Battery recovery (after the
flashlight has been turned off) is also improved. Average on time is
4-6 hours.
The
standard offering is a 0.45"L X 0.3"W X 0.26"H encapsulated
microunit The unit is supplied with 24 AWG 6" colored leads.
Applications
include 2-Cell flashlights, drop-in replacement bulbs for 2-Cell PR based
lamps, pen lights, solar powered lighting, road markers and signal flasher
units.

Key
Benefits of the 2009 LED Drive Module:
- Cost: The 2004 represents a low
cost, small
option for providing current to LEDs with forward voltage in excess of
the supply voltage.
- Longevity: The 2004's output
follows the voltage
of the batteries, but in a manner that provides more light during the
mid-life of the batteries The unit
can turn on with as little as 0.8V.
- Design ease: Ask about our
matching array designs for use with this product.
- Safety: The unit is
surrounded by isolative
epoxy and is water resistant. The unit is short circuit and open
circuit tolerant.
