    3A 2MHz Integrated Switch
    Buck Regulator with 6Vmax Input General Description Features The Micrel MIC4724 is a high efficiency PWM buck (stepdown) regulator that provides up to 3A of output current.
    The MIC4724 operates at 2.0MHz and has proprietary
    internal compensation that allows a closed loop bandwidth
    of over 200KHz.
    The low on-resistance internal p-channel MOSFET of the
    MIC4724 allows efficiencies over 92%, reduces external
    components count and eliminates the need for an
    expensive current sense resistor.
    The MIC4724 operates from 3.0V to 6.0V input and the
    output can be adjusted down to 1V. The devices can
    operate with a maximum duty cycle of 100% for use in lowdropout conditions.
    The MIC4724 is available in 10-pin ePAD MSOP package
    with a junction operating range from –40°C to +125°C.
