Measurements

Single mode buck driver
Tested with Cree XP-G2 led
Diameter: 17mm
Thickness: 6mm

This driver is a buck chip (AX2002) with surrounding components, there is no microprocessor or other stuff on the board. This makes it very easy to change led current, in the datasheet for the AX2002 chip there is a resistance table with values from 20mA and up to 1.5A led current. On the board the resistor is just beside the black wire.

The driver starts at around 3.4 volt and because there is no low voltage warnings or anything it works exactly the same with increasing voltage as with decreasing voltage.

High

There is no noise in the output.



Conclusion

This is a simple driver for people that do not want modes, but just light.
