    2A Integrated Switch Synchronous
    Buck Regulator with Frequency
    Programmable from 800kHz to 4MHz General Description Features The Micrel MIC22200 is a high-efficiency, 2A integrated
    switch synchronous buck (step-down) regulator. The
    MIC22200 switching frequency is programmable from
    800kHz to 4MHz, allowing the customer to optimize their
    designs either for efficiency or for the smallest footprint.
    The regulator achieves efficiencies as high as 95% while
    still switching at 1MHz over a broad load range.
    The ultra high-speed control loops keep the output voltage
    within regulation even under the 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 MIC22200 offers a full range of sequencing and
    tracking options. The EN/DLY pin, combined with the
    Power-On-Reset (POR) pin, allows multiple outputs to be
    sequenced in many ways during turn on and turn off. The
    RC (ramp control) pin allows the device to be connected to
    another device in the MIC22X00 family of products to keep
    the output voltages within a certain delta V on start up.
