    High-Efficiency 2MHz Synchronous Buck Converter General Description Features The Micrel MIC2204 is a high-efficiency, 2MHz PWM synchronous buck switching regulator. Power conversion efficiency of above 95% is easily obtainable over a wide range
    of applications. A proprietary internal compensation technique ensures stability with the smallest possible inductor
    and ceramic output capacitor. The MIC2204 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 1V. The MIC2204
    implements a constant 2MHz pulse-width-modulation (PWM)
    control scheme which reduces spurious noise in sensitive RF
    and communication applications. Additionally, the MIC2204
    can be synchronized to an external clock, or multiple MIC2204s
    can easily be daisy-chained with the SYNCLOCK feature.
    The MIC2204 has a high bandwidth loop (typ. 200kHz) which
    allows ultra-fast transient response times. This is very useful
    when powering applications that require fast dynamic responses, such as the CPU cores and RF circuitry in highperformance cellular phones and PDAs. Input voltage range: 2.3V to 5.5V
    Output down to 1V/ 600mA
