    MIC23303
    4MHz PWM 3A Buck Regulator with
    HyperLight Load™ and Power Good General Description Features The MIC23303 is a high-efficiency 4MHz 3A 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 MIC23303
    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 3mm × 3mm
    DFN package saves precious board space and requires
    only six external components. The MIC23303 is designed for use with a very small
    inductor, down to 0.33µH, and an output capacitor as small
    as 10µF that enables a total solution size less than 1mm in
    height.
    The MIC23303 has very low quiescent current of 24µA and
    can achieve peak efficiency of 93% in continuous
    conduction mode. In discontinuous conduction mode, the
    MIC23303 can achieve 80% efficiency at 1mA.
    The MIC23303 is available in a 12-pin 3mm × 3mm DFN
    package with an operating junction temperature range
    from –40°C to +125°C.
