    MIC2186 Micrel, Inc. MIC2186
    Low Voltage PWM Control IC General Description Features Micrel’s MIC2186 is a high efficiency boost PWM control IC.
    With its wide input voltage range of 2.9V to 14V, the MIC2186
    can be used to efficiently boost voltages in 1-or 2-cell Li Ion
    battery powered applications, as well as to boost voltages in
    fixed 3.3V, 5V, or 12V systems. Its powerful 1.6Ω output
    driver allows the MIC2186 to supply large output currents with
    the selection of proper external MOSFETs.
    The MIC2186 can be configured to operate at 100kHz,
    200kHz, or 400kHz. With it’s fixed frequency PWM architecture, and easily synchronized drive, the MIC2186 is ideal for
    noise-sensitive telecommunications applications.
    MIC2186 also features a low current shutdown mode of
    0.5µA and programmable undervoltage lockout. A manually
    selectable SKIP Mode allows high efficiencies in light load
    situations.
    The MIC2186 is available in 16 pin SOIC and QSOP package
    options with an operating range from –40°C to 125°C. Input voltage range: 2.9V to 14V
    1.6Ω output driver
    Oscillator frequency of 100kHz/200kHz/400kHz
    Frequency sync to 600kHz
    Front edge blanking
    PWM Current Mode Control
    Selectable light load SKIP mode ...
