Shame on you. With 4 x NiMH cells ability to select modes is lost about when the cells need to be recharged. P7 "3 amp" 3-mode driver. $12.01. http://www.taskled.com/techfatman.html Note, Fatman is a Boost regulator (step up), so input voltage must be less than the output voltage to ensure Fatman remains in regulation.
Regulates on voltage or current, output current adjustable from 50-980 mA (or greater by changing set resistor, although that would remove load protection) at maximum 26 V. If your order is NOT shipped the same business day, LEDSupply will offer a 5% discount off your next order. For a boost regulator the Vout has to be higher than the Vin. Battery recovery (after the flashlight has been turned off) is also improved.

The LED is not very bright and I don't measure any Iout (<1mA).

The time now is 02:07 AM. All boards linked may also be available in other quantities or from other suppliers. NOTE: It is important to consider the minimum output voltage of off-line drivers when designing your application. This leads us to finding what input voltage we need for our LEDs.
Buck regulator based on Zetex C310 chip. bFlexV2. $30. Madmax. $13.
Other Boards and Information D2DIM. $20. Drop-in Module List (part 2). Forward Voltage is the amount of volts the light emitting diode requires to conduct electricity and light up. There's also a socket available for them.
Approx. 9-10 V out. Do I need a constant current LED driver or a constant voltage LED driver?

If powered up without a load connected it will NOT be damaged. Constant current output, board available as a "blank" (add set resistor), or preset to 300 mA, 400 mA, 500 mA, 750 mA, or 1000 mA. Assembled BLUE Shark with Remora UI. $55. All rights reserved.
Fatman must never be powered up without a load connected or it will be damaged.

I just ran some numbers through for the MAXIM 1675 and with Vin 2.3V and Iout 20mA I measured an efficiency of 87%. LED Driver List - now database driven and with new search features.

One thought was that all my LEDs can be run off 5VDC so would it be sensible to use a power drop from 24V to 5V in order to use the
