    10A Integrated Switch Synchronous
    Buck Regulator with Frequency
    Programmable to 2MHz General Description Features The Micrel MIC22950 is a high-efficiency 10A integrated
    switch, synchronous buck (step-down) regulator. The
    MIC22950 switching frequency is programmable from
    400kHz to 2MHz, allowing the customer to optimize
    designing either for efficiency or for the smallest footprint.
    The MIC22950 achieves over 95% efficiency while still
    switching at 2MHz 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 low voltage ASICs.
    The output voltage can be adjusted down to 0.7V in order
    to address all low-voltage power needs.
    The MIC22950 features a full range of sequencing and
    tracking options. The EN/DLY and the DELAY pins,
    combined with the POR/PG pin, allow multiple outputs to
    be sequenced in several ways during turn-on and turn-off
    by using EN pin. The RC (Ramp Controlв„ў) pin allows the
    device to be connected to any another device in the
    MIC22x00 family of products, to keep the output voltages
    within a certain delta V during start-up. ...
