    SuperSwitcher IITM General Description Features The Micrel MIC26400 is a constant-frequency, synchronous
    buck regulator featuring a unique digitally modified adaptive
    ON-time control architecture. The MIC26400 operates over
    an input supply range of 4.5V to 26V and provides a
    regulated output at up to 5A of output current. The output
    voltage is adjustable down to 0.8V with a typical accuracy of
    В±1%, and the device operates at a switching frequency of
    300kHz.
    Micrel’s Hyper Speed ControlTM 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 MIC26400 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.
