    Synchronous DC/DC Buck Regulator
    SuperSwitcher IIGв„ў General Description Features The Micrel MIC261203 is a constant-frequency,
    synchronous DC/DC buck regulator featuring adaptive ontime control architecture. The MIC261203 operates over a
    supply range of 4.5V to 28V. It has an internal linear
    regulator which provides a regulated 5V to power the
    internal control circuitry. MIC261203 operates at a
    constant 600kHz switching frequency in continuousconduction mode and can be used to provide up to 12A of
    output current. The output voltage is adjustable down to
    0.8V. Hyper Light Load™ efficiency – up to 80% at 10mA
    Hyper Speed Controlв„ў architecture enables
    -High Delta V operation (VIN = 28V and VOUT = 0.8V)
    -Small output capacitance
    Input voltage range: 4.5V to 28V
    Output current up to 12A
    Up to 95% efficiency
    Adjustable output voltage from 0.8V to 5.5V
    В±1% FB accuracy
    Any CapacitorTM stable -zero-to-high ESR
    600kHz switching frequency
    Power Good (PG) output
    Foldback current-limit and “hiccup” mode short-circuit ...
