    MIC2185 Micrel, Inc. MIC2185
    Low Voltage Synchronous Boost PWM Control IC General Description Features Micrel’s MIC2185 is a high efficiency synchronous boost
    PWM control IC. With its wide input voltage range of 2.9V to
    14V, the MIC2185 can be used to efficiently boost voltages
    in 1-or 2-cell Li Ion battery powered applications, as well as
    fixed 3.3V and 5V systems. Its powerful 5Ω output drivers
    allow the MIC2185 to supply large output currents with the
    selection of the proper external MOSFETs.
    With it’s fixed frequency PWM architecture, and easily
    synchronized drive, the MIC2185 is ideal for noise-sensitive telecommunications applications. The nominal 400kHz
    operating frequency of the MIC2185 can be divided by two,
    allowing the device to be externally synchronized to frequencies below 400kHz.
    The MIC2185 also features a low current shutdown mode
    and a programmable undervoltage lockout. A skipped pulse
    mode of operation can be manually set to achieve higher
    efficiencies at light load conditions.
    The MIC2185 is available in a 16 pin SOIC package and 16
    pin QSOP package with an ambient temperature operating
    range from –40°C to 85°C. Input voltage range: 2.9V to 14V
    95% efficiency
    Oscillator frequency of 200kHz/400kHz
    Frequency sync to 600kHz
    0.5µA shutdown current ...
