    Hello,

    I've looked for, but not found.
    Is someone knowing what is the reference of a tiny 6 pins SMD chip
    marked "AL207"?

    It dosn't work (it's a tiny boost - or step up - dc dc converter's),
    because since it's a little surface mount chip, what is marked on is a
    sort of code which could be not unique at all, not the chip's name.

    XCL207?

    6 pin Dc/DC converter

    If it's not the XCL207 mentioned by Archon, check the various 'SMD
    Marking code' lists.

    Could be that, but sadly no because it has no internal inductor, and
    it's a step-up (the XCL207 is for step-down).

    Tried that, but I don't find it on whatever list I knew or with google...

    Looking at the data sheet for that part it seems the smd package
    labeling bears no resemblance to chip number anyway, so you are going to
    have to get more info, actual package size type may narrow it down,
    some idea of its input voltage and expected output voltage. Whats the
    device its in? JC

    It's the chip on this board :

    It was close, but there is a external diode and the pinouts dosn't
    correspond. The component i'm looking for have :
    _____
    SW -| |- ??? (to GND by 10k resistor)
    GND -| |- Vin or enable
    FB -|_____|- enable or Vin

    So the chip is the one on the board


    http://www.ebay.com/itm/New-DC-DC-C...-1A-USB-Charger-F-MP3-MP4-Phone-/140891808636

    priced at $2.59 for the board, so i guess you are not trying to repair a
    $2.59 board, so why not buy the cheapo board and take the chip? JC

    Because I wanted to read the real datasheet (and know the exacts
    characteristics) before using it in my projects...
