    Precision Current Limit SOIC-8
    SuperSwitcherв„ў Buck Regulator General Description Features The MIC4682 is an easy-to-use step-down (buck) switch Programmable output current limit
    mode voltage regulator. It features a programmable
    – 10% accuracy over temperature
    current limit that allows 10% current limit accuracy over its Wide 4V to 34V operating input voltage range
    full operating temperature range. The precision current Fixed 200kHz PWM operation
    limit makes the MIC4682 ideal for constant-voltage Power SOIC-8 package allows 2A continuous output
    constant-current applications, such as simple battery
    chargers. The precision current limit also gives designers
    the ability to set the maximum output current below the All surface mount solution
    saturation current rating of the inductor. This allows the Internally compensated
    use of the smallest possible inductors for a given Less than 1ВµA typical shutdown-mode current
    application, saving valuable space and cost. Thermal shutdown protection
    The MIC4682 is a very robust device. Its 4V to 34V input
    voltage range allows the MIC4682 to safely be used in
    applications where voltage transients may be present.
    Additional protection features include cycle-by-cycle Battery chargers
    current limiting and over-temperature shutdown. The White LED drivers
    MIC4682 is available in a thermally optimized power
    SOIC-8 package that allows it to achieve 2A of continuous Constant voltage constant current step-down ...
