  • Good and cheap one mode driver

    Involvement:General (knows how to use it) - Ownership:1 day to 1 week

    Pros:

    - Small and cheap driver.

    - It's can be driven more than one LED.

    - It's can be driven many LED type.

    Cons:

    - The pre-soldered wires is too thin (I changed them to thicker wires).

    OtherThoughts:

    The top of the IC is polished, but I think, this is came with AX2002 (the driver board color is red).

    It's a one mode, good efficiency switching driver. The diode is SS34 (3A current limit).

    If you change the sense resistor to 0.125 ohm, the output current is changed to 2A (the AX2002 has 0.25V feedback voltage).

    I use this driver with two serial connected 18650 battery.

    Bottomline:

    I waited three months for it, but it was worth.
