    Synchronous DC-DC Buck Regulator
    SuperSwitcher IIв„ў General Description Features The Micrel MIC27600 is a constant-frequency, synchronous
    buck regulator featuring a unique digitally-modified adaptive
    on-time control architecture. The MIC27600 operates over an
    input supply range of 4.5V to 36V and provides a regulated
    output of up to 7A of output current. The output voltage is
    adjustable down to 0.8V with a guaranteed accuracy of В±1%,
    and the device operates at a switching frequency of 300kHz. 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 digitally modified adaptive tON ripple control architecture
    combines the advantages of fixed-frequency operation and
    fast transient response in a single device.
    The MIC27600 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 = 36V and VOUT = 0.8V)
    -Small output capacitance ...
