    Hyper Speed ControlВ® 3A Buck Regulator
    Features General Description The MIC4930 is a high-efficiency, 3A synchronous
    buck regulator with ultra-fast transient response
    perfectly suited for supplying processor core and I/O
    voltages from a 5V or 3.3V bus. The MIC4930 provides
    a switching frequency up to 3.3 MHz while achieving
    peak efficiencies up to 95%. An additional benefit of
    high-frequency operation is very low output ripple
    voltage throughout the entire load range with the use of
    a small output capacitor. The MIC4930 is designed for
    use with a very small inductor, down to 1 ОјH, and an
    output ceramic capacitor as small as 10 ОјF without the
    need for external ripple injection. A wide range of
    output capacitor types and values can also be
    accommodated. Input Voltage: 2.7V to 5.5V
    3A Output Current
    Up To 95% Efficiency
    Up To 3.3 MHz Operation
    Safe Start-Up into a Pre-Biased Output
    Power Good Output
    Ultra-Fast Transient Response
    Low Output Voltage Ripple ...
