    MIC23450
    3MHz, PWM, 2A Triple Buck Regulator
    with HyperLight Load® and Power Good General Description
    The MIC23450 is a high-efficiency, 3MHz, triple 2A,
    ®
    synchronous buck regulator with HyperLight Load mode.
    HyperLight Load 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 5mm x 5mm QFN package
    saves board space and requires only five external
    components for each channel.
    The MIC23450 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
    height.
    The MIC23450 has a very-low quiescent current of 23µA
    each channel and achieves as high as 81% efficiency at
    1mA. At higher loads, the MIC23450 provides a constant
    switching frequency around 3MHz while achieving peak
    efficiencies up to 93%. ...
