    MIC2194 Micrel MIC2194
    400kHz SO-8 Buck Control IC General Description Features Micrel’s MIC2194 is a high efficiency PWM buck control IC
    housed in the SO-8 package. Its 2.9V to 14V input voltage
    range allows it to efficiently step down voltages in 3.3V, 5V,
    and 12V systems as well as 1-or 2-cell Li Ion battery powered
    applications. The flexible architecture of the MIC2194 allows
    for it to be configured as a buck or a buck-boost converter.
    The MIC2194 solution saves valuable board space. The
    device is housed in the space-saving SO-8 package, whose
    low pin-count minimizes external components. Its 400kHz
    PWM operation allows a small inductor and small output
    capacitors to be used. The MIC2194 can implement allceramic capacitor solutions.
    The MIC2194 drives a high-side P-channel MOSFET. A low
    output driver impedance of 2Ω allows the MIC2194 to drive
    large external MOSFETs to generate a wide range of output
    currents. The MIC2194 can achieve maximum duty cycles of
    100%, which can be useful in low headroom applications.
    The MIC2194 is available in an 8 pin SOIC package with a
    junction temperature range of –40°C to +125°C. 2.9V to 14V input voltage range
