    MIC24056
    12V, 12A High-Efficiency Buck Regulator
    SuperSwitcher II General Description Features HyperLight Load efficiency – up to 80% at 10mA
    The Micrel MIC24056 is a constant-frequency,
    synchronous DC/DC buck regulator featuring adaptive on Hyper Speed Control architecture enables
    time control architecture. The MIC24056 operates over a
    -High delta V operation (VIN = 19V and VOUT = 0.8V)
    supply range of 4.5V to 19V. It has an internal linear
    -Small output capacitance
    regulator which provides a regulated 5V to power the Input voltage range: 4.5V to 19V
    internal control circuitry. MIC24056 operates at a constant
    600kHz switching frequency in continuous-conduction Output current up to 12A
    mode and can be used to provide up to 12A of output Up to 95% efficiency
    current. The output voltage is adjustable down to 0.8V. Adjustable output voltage from 0.8V to 5.5V

    Micrel’s HyperLight Load architecture provides the same ±1% FB accuracy
    high efficiency and ultra-fast transient response as the Any Capacitor™ stable -zero-to-high ESR
    Hyper Speed Control architecture under medium to 600kHz switching frequency
    heavy loads, but also maintains high efficiency under light
    load conditions by transitioning to variable frequency, Power good (PG) output
    discontinuous mode operation. Foldback current-limit and “hiccup” mode short-circuit
