  • Very efficient but output different in my samples

    Very eficient driver, provides enough current but depending on the setup it can become too much.
    The re is only one working mode (on/off) and for me this is a plus.


    Comparing the 4 regulators i received with the same batteries and a Z-led and from 4 NiMH batteries i got 1150ma,950ma and 850ma from the other two.


    I tried the trick mentioned below that you can scratch the output resistor (20m ohm) slowly and when the circuit is not powered and reduce the output current


    They are cheap enough so you can try them
