    MIC23155
    3MHz PWM 2A Buck Regulator with
    HyperLight Load® and Power Good General Description Features The MIC23155 is a high-efficiency 3MHz 2A synchronous
    buck regulator with HyperLight Load mode, power good
    output indicator, and programmable soft start. HyperLight
    Load provides very high efficiency at light loads and ultrafast transient response which makes the MIC23155
    perfectly suited for supplying processor core voltages. An
    additional benefit of this proprietary architecture is very low
    output ripple voltage throughout the entire load range with
    the use of small output capacitors. The tiny 2.5mm x
    2.5mm Thin DFN package saves precious board space
    and requires only four external components.
    The MIC23155 is designed for use with a very small
    inductor, down to 0.47µH, and an output capacitor as small
    as 2.2µF that enables a total solution size, less than 1mm
    in height.
    The MIC23155 has a very low quiescent current of 22µA
    and achieves a peak efficiency of 94% in continuous
    conduction mode. In discontinuous conduction mode, the
    MIC23155 can achieve 85% efficiency at 1mA.
    The MIC23155 is available in a 10-pin 2.5mm x 2.5mm
    Thin DFN package with an operating junction temperature
    range from –40°C to +125°C. ...
