    MIC22405
    4A Integrated Switch High-Efficiency
    Synchronous Buck Regulator with
    Frequency Programmable upto 4MHz General Description Features The Micrel MIC22405 is a high efficiency, 4A integrated
    switch synchronous buck (step-down) regulator. The
    MIC22405 is optimized for highest efficiency, achieving
    more than 95% efficiency while still switching at 1MHz.
    The ultra-high speed control loop keeps the output voltage
    within regulation even under the extreme transient load
    swings commonly found in FPGAs and low-voltage ASICs.
    The output voltage is pre-bias safe and can be adjusted
    down to 0.7V to address all low-voltage power needs.
    The MIC22405 offers a full range of sequencing and
    tracking options. The Enable/Delay (EN/DLY) pin,
    combined with the Power Good (PG) pin, allows multiple
    outputs to be sequenced in any way during turn-on and
    turn-off. The Ramp Controlв„ў (RC) 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 MIC22405 is available in a 20-pin 3mm x 4mm MLF
    with a junction operating range from –40°C to +125°C. ...
