    USB Power Maximizerв„ў General Description Features The MIC2267 is a USB Power Maximizerв„ў which
    transfers the maximum power from the limited USB current
    source by shaping the input current limit profile. It
    incorporates a high efficiency, integrated synchronous step
    down regulator. Internal 150mΩ switches and adjustable
    operating frequency allows the MIC2267 to achieve
    greater than 90% efficiency across a broad load range. It
    replaces the USB current limit switch, 5V buck regulator
    and minimizes capacitance for many USB applications.
    The adjustable frequency control can be utilized to move
    harmonics away from sensitive frequency bands.
    The MIC2267 allows the input current limit profile to be
    shaped for various applications. With a current mode
    control with external compensation, the MIC2267 transient
    response can be optimized over load and output
    capacitance making it highly flexible for many applications.
    Additional features include 1ВµA shutdown current, output
    current limit and thermal shutdown protection. The
    MIC2267 is available in a 12-pin 3mm x 3mm MLFВ® with a
    junction operating range from –40°C to +125°C. ...
