    Hyper Speed Controlв„ў 5A Buck Regulator General Description
    The MIC4950 is a high-efficiency, 5A synchronous buck
    regulator with ultra-fast transient response. It is perfectly
    suited for supplying processor core and I/O voltages from
    a 5V or 3.3V bus. The MIC4950 provides a switching
    frequency up to 3.3MHz while achieving peak efficiencies
    up to 95%. An additional benefit of high-frequency
    operation is very low output ripple voltage throughout the
    entire load range with the use of a small output capacitor.
    The MIC4950 is designed for use with a very small
    inductor, down to 1ВµH, and an output ceramic capacitor as
    small as 10ВµF, without the need for external ripple
    injection. A wide range of output capacitor types and
    values can also be accommodated.
    The MIC4950 supports safe start-up into a pre-biased
    output, and offers short-circuit and thermal shutdown
    protections.
    The MIC4950 is available in 8-Pin SOIC and 10-Pin 3mm
    Г— 4mm DFN packages with an operating junction
    temperature range from –40°C to +125°C.
