    MIC28511
    60VIN, 3A Synchronous Buck Regulator
    Features General Description 4.6V to 60V Operating Input Voltage Supply Up to 3A Output Current Integrated High-Side and Low-Side N-Channel
    MOSFETs HyperLight LoadВ® (MIC28511-1) and Hyper
    Speed ControlВ® (MIC28511-2) Architecture Enable Input and Power Good (PGOOD) Output Programmable Current-Limit and Foldback
    “Hiccup” Mode Short-Circuit Protection Built-In 5V Regulator for Single-Supply Operation Adjustable 200 kHz to 680 kHz Switching
    Frequency Fixed 5 ms Soft-Start Internal Compensation and Thermal Shutdown Thermally-Enhanced 24-Pin 3 mm x 4 mm FQFN
    Package –40°C to +125°C Junction Temperature Range The MIC28511 is a synchronous step-down switching
    regulator with internal power switches capable of
    providing up to 3A output current from a wide input
    supply range from 4.6V to 60V. The output voltage is
    adjustable down to 0.8V with a guaranteed accuracy of
    В±1%. A constant switching frequency can be
    programmed from 200 kHz to 680 kHz. The Hyper
    Speed ControlВ® and HyperLight LoadВ® architectures of
    the MIC28511 allow for high VIN (low VOUT) operation
    and ultra-fast transient response while reducing the
    required output capacitance and providing very good
    light-load efficiency.
    The MIC28511 offers a full suite of features to ensure
    protection under fault conditions. These include
    undervoltage lockout to ensure proper operation under
    power sag conditions, internal soft-start to reduce ...
