    MIC28512
    70V, 2A Synchronous Buck Regulator
    Features General Description 4.6V to 70V Operating Input Voltage Supply Up to 2A Output Current Integrated High-Side and Low-Side N-Channel
    MOSFETs HyperLight Load (MIC28512-1) and Hyper Speed
    Control (MIC28512-2) 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
    FCQFN Package –40°C to +125°C Junction Temperature Range The MIC28512 is a synchronous step-down switching
    regulator with internal power switches capable of
    providing up to 2A output current from a wide input
    supply range from 4.6V to 70V. The output voltage is
    adjustable down to 0.8V with a guaranteed accuracy of
    ±1%. A constant switching frequency can be
    programmed from 200 kHz to 680 kHz. The Hyper
    Speed Control® and HyperLight Load® architectures of
    the MIC28512 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 MIC28512 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 ...
