    4MHz PWM 1.2A Internal Inductor
    Buck Regulator with HyperLight Loadв„ў
    and Power Good General Description Features The MIC33153 is a high-efficiency 4MHz 1.2A
    synchronous buck regulator with an internal inductor,
    HyperLight Loadв„ў mode, Power Good (PG) output
    indicator, and programmable soft start. HyperLight Loadв„ў
    provides very high efficiency at light loads and ultra-fast
    transient response which makes the MIC33153 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 MIC33153 is designed so that only two external
    capacitors as small as 2.2ВµF are needed for stability. This
    gives the MIC33153 the ease of use of an LDO with the
    efficiency of a HyperLight Loadв„ў DC converter. The
    MIC33153 achieves efficiency in HyperLight Load mode
    as high as 85% at 1mA, with a very low quiescent current
    of 22ВµA. At higher loads, the MIC33153 provides a
    constant switching frequency up to 4MHz.
    The MIC33153 is available in 14-pin 3.0mm x 3.5mm ...
