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

    Pros:

    Good for driving CREE Led / Seoul LEDs. Does provide maximum brightness only when input voltage > 6V.

    Provides > 350ma with 3.5 V input.

    Cons:

    Output current is limited to input voltage and the type of LED connected... for e.g. provides more current with SSC U Bin than CREE P4 bin.

    OtherThoughts:

    Great value, apparently high efficieny (94%)

    Better than linear (LDO low drop out voltage) regulators.

    Bottomline:

    Good Value for driving LED over a wide range of input voltages.
