- Total input voltage must be 1-3V higher than output voltage, depending on the number of LED that you need. If you are running two LED, your battery voltage should ~2V higher than the LED total VF. If you are running one LED, your battery voltage should be ~1V higher than the LED VF.

- Output current is fixed on this driver to 1000mA. Output voltage, input voltage, and input current are variable.

- Case 1: Use one CREE XR-E LED that consumes VF: 3.5V and 750mA with four 18650 battery. The input voltage will be around 12V, with the input current is about 200mA. (10 hours runtime on current regulated 750mA)

- Case 2: Use three CREE XR-E LED that needs VF: 10.5V and 750mA (each) with four 123A battery. The input voltage will be around 16V, with input current of around 500mA. (about 1.5 hours of runtime on current regulated 750mA- 400+ constant lumens)

This LED driver is a must have for flashlight DIYers that mess with multiple LEDs.

Power three SSC U-Bin LEDs with three or four RCR123A or four 18650 li-ion cell. Current output is regulated at 750mA to ensure constant light ouput.


* Notes, the MCU's pin (a total of eight pins) which is the closest to the negative LED output, is treated as negative LED output as well. Multi-volt meter reads zero ohms between them.

Dimension: 17mm(Dia.) x 1.6mm(Thickness) x 6mm(H) (including component)
