    MIC23153 - 4MHz PWM 2A Buck Regulator with HyperLight LoadВ® and Power Good
    Docket ↓
    4MHz PWM 2A Buck Regulator with
    HyperLight Loadв„ў and Power Good General Description Features The MIC23153 is a high-efficiency, 4MHz, 2A,
    synchronous buck regulator with HyperLight Loadв„ў mode,
    Power Good output indicator, and programmable soft-start.
    HyperLight Loadв„ў provides very-high efficiency at light
    loads and ultra-fast transient response which makes the
    MIC23153 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 MLF package
    saves precious board space and requires only four
    external components.
    The MIC23153 is designed for use with a very-small
    inductor, down to 0.47ВµH, and an output capacitor as small
    as 2.2 ВµF that enables a total solution size, less than 1mm
    in height.
    The MIC23153 has a very-low quiescent current of 22ВµA
    and achieves a peak efficiency of 93% in continuous
    conduction mode. In discontinuous conduction mode, the
    MIC23153 can achieve 85% efficiency at 1mA. ...
