    High Efficiency 1MHz Synchronous
    Buck Regulator General Description Features The Micrel MIC2203 is a high efficiency 1MHz PWM
    synchronous buck switching regulator. The MIC2203
    features low noise constant frequency PWM
    operation with a low dynamic supply current of
    <1mA. The low noise and efficient operation both
    make the MIC2203 well suited for sensitive RF, and
    audio power applications.
    The MIC2203 operates from 2.3V to 5.5V input and
    can supply over 300mA of output current with output
    voltages down to 0.5V. Additionally, the MIC2203
    can be synchronized to an external clock, or multiple
    MIC2203s can easily be daisy-chained with the
    SYNCLOCK feature.
    The MIC2203 has a high loop bandwidth with
    corresponding ultra fast transient response times.
    This reduces the output capacitor size, and is very
    useful when powering applications that require fast
    dynamic response such as CPU cores and RF
    circuitry in high performance cellular phones and
    PDAs.
    The MIC2203 is available in 10-pin MSOP and ...
