    75V/4A Hyper Speed Controlв„ў
    Synchronous DC-DC Buck Regulator
    SuperSwitcher IIв„ў General Description Features The Micrel MIC28500 is an adjustable frequency,
    synchronous buck regulator featuring a unique adaptive ontime control architecture. The MIC28500 operates over an
    input supply range of 30V to 75V and provides a regulated
    output of up to 4A of output current. The output voltage is
    adjustable down to 0.8V with a guaranteed accuracy of ±1%. Micrel’s Hyper Speed Control™ architecture allows for ultrafast transient response while reducing the output capacitance
    and also makes (High VIN)/(Low VOUT) operation possible.
    This adaptive tON ripple control architecture combines the
    advantages of fixed-frequency operation and fast transient
    response in a single device.
    The MIC28500 offers a full suite of protection features to
    ensure protection of the IC during fault conditions. These
    include undervoltage lockout to ensure proper operation
    under power-sag conditions, internal soft-start to reduce
    inrush current, foldback current limit, “hiccup” mode shortcircuit protection and thermal shutdown.
    All support documentation can be found on Micrel’s web
    site at: Hyper Speed Controlв„ў architecture enables
    -High Delta V operation (VIN = 75V and VOUT = 0.8V)
    -Small output capacitance
