  • Very efficient but output different in my samples

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

    Pros:

    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.

    Cons:

    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.

    OtherThoughts:

    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

    Bottomline:

    They are cheap enough so you can try them
