    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
