    MIC2193 Micrel MIC2193
    400kHz SO-8 Synchronous Buck Control IC General Description Features Micrel’s MIC2193 is a high efficiency, PWM synchronous
    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 MIC2193 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 MIC2193 can implement allceramic capacitor solutions.
    The MIC2193 drives a high-side P-channel MOSFET, eliminating the need for high-side boot-strap circuitry. This feature
    allows the MIC2193 to achieve maximum duty cycles of
    100%, which can be useful in low headroom applications. A
    low output driver impedance of 4Ω allows the MIC2193 to
    drive large external MOSFETs to generate a wide range of
    output currents.
    The MIC2193 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
    400kHz oscillator frequency
