    1MHz PWM Synchronous Buck Control IC General Description Features The MIC2168 is a high-efficiency, simple to use 1MHz PWM
    synchronous buck control IC housed in a small MSOP-10
    package. The MIC2168 allows compact DC/DC solutions
    with a minimal external component count and cost.
    The MIC2168 operates from a 3V to 14.5V input, without
    the need of any additional bias voltage. The output voltage
    can be precisely regulated down to 0.8V. The adaptive all
    N-Channel MOSFET drive scheme allows efficiencies over
    95% across a wide load range.
    The MIC2168 senses current across the high-side N-Channel MOSFET, eliminating the need for an expensive and
    lossy current-sense resistor. Current limit accuracy is maintained by a positive temperature coefficient that tracks the
    increasing RDS(ON) of the external MOSFET. Further cost
    and space are saved by the internal in-rush-current limiting
    digital soft-start.
    The MIC2168 is available in a 10-pin MSOP package, with a
    wide junction operating range of –40°C to +125°C.
