    Synchronous DC-to-DC Buck Regulator
    SuperSwitcherв„ў II General Description
    The Micrel MIC261203-ZA is a constant-frequency,
    synchronous buck regulator featuring a unique adaptive
    on-time control architecture. The MIC261203-ZA operates
    over an input supply range of 4.5V to 28V and provides a
    regulated output of up to 12A of output current. The output
    voltage is adjustable down to 0.6V with a guaranteed
    accuracy of В±1%, and the device operates at a switching
    frequency of 600kHz.
    Micrel’s Hyper Speed Control architecture allows for
    ultra-fast 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 MIC261203-ZA offers a full suite of 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” short-circuit ...
