    500kHz PWM Synchronous Buck Control IC General Description Features The MIC2169 is a high-efficiency, simple to use 500kHz PWM
    synchronous buck control IC housed in a small MSOP-10
    package. The MIC2169 allows compact DC/DC solutions
    with a minimal external component count and cost.
    The MIC2169 operates using a 3V to 14.5V input, without
    the need for 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 MIC2169 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
    via a positive temperature coefficient that tracks the increasing RDS(ON) of the external MOSFET. Additional cost and
    space are saved by the internal in-rush-current limiting and
    digital soft-start.
    The MIC2169 is available in a 10-pin MSOP package, with a
    wide junction operating range of –40°C to +125°C.
