    MIC22400
    4A Integrated Switch Synchronous
    Buck Regulator with Frequency
    Programmable up to 4MHz General Description
    The Micrel MIC22400 is a high-efficiency, 4A integrated
    switch synchronous buck (step-down) regulator. The
    MIC22400 is optimized for highest efficiency, achieving
    over 90% efficiency while still switching at 1MHz over a
    broad load range. The ultra-high-speed control loop keeps
    the output voltage within regulation even under extreme
    transient load swings commonly found in FPGAs and lowvoltage ASICs. The output voltage can be adjusted down
    to 0.7V to address all low-voltage power needs. The
    MIC22400 gives a full range of sequencing and tracking
    options. The EN/DLY pin combined with the Power-OnReset (POR) pin allows multiple outputs to be sequenced
    in any way on turn-on and turn-off. The Ramp Control™
    (RC) pin allows the device to be connected to another
    MIC22400 family of products to keep the output voltages
    within a certain ΔV on start-up.
    ®
    The MIC22400 is available in a 20-pin 3mm x 4mm MLF
    and thermally-enhanced 20-pin ePad TSSOP with a
    junction operating range from –40°C to +125°C.
