    12V, 9A High-Efficiency Buck Regulator
    SuperSwitcher II General Description Features Hyper Light Load efficiency – up to 80% at 10mA
    The Micrel MIC24054 is a constant-frequency,
    synchronous DC/DC buck regulator featuring adaptive on Hyper Speed Control architecture enables
    time control architecture. The MIC24054 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. The MIC24054 operates at a
    constant 600kHz switching frequency in continuous Output current up to 9A
    conduction mode and can be used to provide up to 9A of Up to 95% efficiency
    output current. The output voltage is adjustable down to Adjustable output voltage from 0.8V to 5.5V
    0.8V. В±1% FB accuracy
