    MIC23031
    4MHz PWM 400mA Buck Regulator with
    HyperLight Loadв„ў General Description Features The MIC23031 is a high-efficiency 4MHz 400mA
    synchronous buck regulator with HyperLight Loadв„ў mode.
    HyperLight Loadв„ў provides very-high efficiency at light
    loads and ultra-fast transient response which is 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 1.6mm x 1.6mm Thin
    MLFВ® package saves precious board space and requires
    only three external components.
    The MIC23031 is designed for use with a very-small
    inductor, down to 0.47ВµH, and an output capacitor as small
    as 2.2ВµF that enables a sub-1mm height.
    The MIC23031 has a very-low quiescent current of 21ВµA
    and achieves as high as 88% efficiency at 1mA. At higher
    loads, the MIC23031 provides a constant switching
    frequency around 4MHz while achieving peak efficiencies
    up to 93%.
    The MIC23031 is available in a 6-pin 1.6mm x 1.6mm Thin
    MLFВ® package with an operating junction temperature
    range from –40°C to +125°C. ...
