    driver help

    I purchased a adjustable boost driver for a 445nm build but iv'e hit a problem, when i connected it up to a test load it blew a chip and smoked badly. I just made the test load and it's soldered fine and exactly the same as all the ones iv'e seen it's got me stumped help appreciated.
