    1MHz, 7A Integrated Switch HighEfficiency Synchronous Buck Regulator General Description
    The Micrel MIC22700 is a high-efficiency, 7A, integrated
    switch, synchronous buck (step-down) regulator. The
    MIC22700 is optimized for highest efficiency, achieving
    more than 95% efficiency while still switching at 1MHz
    over a broad range. The device works with a small 1µH
    inductor and 100µF output capacitor. The ultra-high speed
    control loop keeps the output voltage within regulation
    even under extreme transient load swings commonly
    found in FPGAs and low-voltage ASICs. The output
    voltage can be adjusted down to 0.7V to address all low
    voltage power needs. The MIC22700 offers a full range of
    sequencing and tracking options. The Enable/Delay pin
    combined with the Power Good/POR pin allows multiple
    outputs to be sequenced in any way during turn-on and
    turn-off. The RC (Ramp Control™) pin allows the device to
    be connected to another product in the MIC22xxx and/or
    MIC68xxx family, to keep the output voltages within a
    certain ∆V on start up.
    The MIC22700 is available in a 24-pin 4mm x 4mm MLF
    with a junction operating range from –40°C to +125°C. ...
