2009A-HI

The 2009A MicroPuck is a versatile, compact solution for powering (1) High-Power LED from low DC voltages. The 2009A was designed to power (1) High-Power LED, or strings of 5mm (T 1-3/4) LEDs, efficiently and with stability. This LED driver provides 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 by the LED much longer than conventional flashlights. Battery recovery (after the flashlight has been turned off) is also improved.

Drives 1 power led  or up to 8 series connected T 1-13/4 LEDs. You can also use these for High Power Leds if you want to underdrive them

• Designed to operate with 2 series connected cells
• Optimizes battery life
• Short-circuit and open-circuit tolerant
• Fully encapsulated construction
• 0.45″L x 0.3″W x 0.26″H
