    1A 200kHz SuperSwitcherв„ў
    Buck Regulator General Description Features The MIC4680 SuperSwitcherв„ў is an easy-to-use fixed or
    adjustable output voltage step-down (buck) switch-mode
    voltage regulator. The 200kHz MIC4680 achieves up to
    1.3A of continuous output current over a wide input range
    in a 8-pin SOIC.
    The MIC4680 is available in 3.3V and 5V fixed output
    versions or adjustable output down to 1.25V.
    The MIC4680 has an input voltage range of 4V to 34V,
    with excellent line, load, and transient response. The
    regulator performs cycle-by-cycle current limiting and
    thermal shutdown for protection under fault conditions. In
    shutdown mode, the regulator draws less than 2ВµA of
    standby current.
    The MIC4680 SuperSwitcherв„ў regulator requires a minimum number of external components and can operate
    using a standard series of inductors and capacitors.
    Frequency compensation is provided internally for fast
    transient response and ease of use.
    The MIC4680 is available in the 8-pin SOIC with a
    –40°C to +125°C junction temperature range. SOIC-8 package with up to 1.3A output current
    All surface mount solution
    Only 4 external components required ...
