    High Efficiency 2.5W Boost Converter General Description Features The MIC2145 is a small size boost switching regulator that
    can provide over 2.5W of output power. The input voltage
    range is between 2.4V to 16V, making the device suitable for
    one-cell Li-Ion and 3-to 4-cell alkaline/NiCad/NiMH applications. The output voltage of the MIC2145 can be adjusted up
    to 16V.
    The MIC2145 is well suited for portable, space-sensitive
    applications. Its typical 450kHz operation allows small surface mount external components to be used. The MIC2145
    has a low quiescent current of 200µA, and a typical shutdown
    current of 0.5µA. The MIC2145 is capable of high efficiencies
    in a small board area.
    The MIC2145 features a low-on resistance internal switch
    that allows it to provide over 2.5W of output power. The peak
    switch current can be programmed through an external
    resistor. This allows the user to set the peak switch current at
    the level where maximum efficiency occurs. It also allows the
    user to further optimize for efficiency and inductor size by
    setting the peak current below the level of inductor saturation.
    The MIC2145 is available in an MSOP-8 and 3mm×3mm
    MLF™-10L package with an ambient operating temperature
    range from –40°C to +85°C. 2.4V to 16V input voltage
    Output adjustable to 16V
    Programmable peak current limit ...
