    MIC2184 - Low Voltage Buck PWM Control IC

    MIC2184 Micrel, Inc. MIC2184
    Low Voltage Buck PWM Control IC General Description Features Micrel’s MIC2184 is a high efficiency PWM buck control IC.
    With its wide input voltage range of 2.9V to 14V, the MIC2184
    can be used to efficiently step voltages down in 1-or 2-cell Li
    Ion battery powered applications, as well as in fixed 3.3V, 5V,
    or 12V systems.
    Efficiencies over 90% are achievable over a wide range of
    load conditions with the MIC2184’s PWM control scheme.
    The operating frequency can be divided by two by raising the
    FREQ/2 pin to VDD. This allows the user to optimize efficiency
    versus board space. It also allows the MIC2184 to be externally synchronized to frequencies below its nominal 400KHz.
    The MIC2184 features an oscillator output, FreqOut, which
    can be used to implement a simple charge pump in low
    voltage applications. The output of the charge pump can be
    fed into the gate drive power circuitry via the VINP pin,
    allowing enhanced gate drive, hence higher efficiencies,
    despite low input voltages.
    MIC2184 features a 1ВµA shutdown mode, and a programmable undervoltage lockout, making it well suited for portable
    applications.
    The MIC2184 is available in 16 pin SOP and QSOP package
    options with a junction temperture range range from –40°C
    to +125В°C. Input voltage range: 2.9V to 14V
    >90% efficiency ...
