    High Efficiency 2MHz Synchronous Buck
    Converter 1ВµF Stable PWM Regulator General Description Features The Micrel MIC2202 is a high efficiency 2MHz PWM
    synchronous buck regulator. The fast 2MHz operation
    along with a proprietary compensation scheme allows the
    smallest possible external components. The MIC2202 can
    operate with a 1ВµF ceramic output capacitor and a small,
    low DC-resistance, 2.2ВµH inductor, reducing system size
    and cost while allowing a high level of efficiency.
    The MIC2202 operates from 2.3V to 5.5V input and
    features internal power MOSFETs that can supply over
    600mA of output current with output voltages down to
    0.5V. The MIC2202 implements a constant 2MHz pulsewidth-modu-lation (PWM) control scheme which reduces
    noise in sensitive RF, audio, and communications
    applications. Additionally, the MIC2202 can be
    synchronized to an external clock, or multiple MIC2202s
    can easily be daisy-chained with the SYNCLOCK feature.
    The MIC2202 has a high bandwidth loop (up to 500kHz)
    which allows ultra fast transient response times. This 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
    MIC2202 is available in 10-pin MSOP and 10-pin 3mm Г— ...
