    Synchronous DC/DC Buck Regulator
    SuperSwitcher IIв„ў General Description Features The Micrel MIC26901 is a constant-frequency, synchronous
    buck regulator featuring a unique adaptive on-time control
    architecture. The MIC26901 operates over an input supply
    range of 4.5V to 28V and provides a regulated output of up to
    9A 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 600kHz. 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 MIC26901 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. An open-drain
    Power Good (PG) pin is provided.
    All support documentation can be found on Micrel’s web
    site at: www.micrel.com. Hyper Speed Controlв„ў architecture enables
    -High Delta V operation (VIN = 28V and VOUT = 0.8V) ...
