    Portable Equipment General Description
    The MIC2877 is a compact and highly efficient 2 MHz
    synchronous boost regulator with a typically 6.5A
    switch. It features a bidirectional true load disconnect
    function that prevents any leakage current between the
    input and output when the device is disabled
    (EN = GND), it protects the input supply and improves
    the start-up performance.
    The MIC2877 has the input voltage range between ...
