    500kHz PWM Synchronous Buck Control IC General Description Features The MIC2169A is a high-efficiency, simple to use 500kHz
    PWM synchronous buck control IC housed in a small MSOP10 package. The MIC2169A allows compact DC/DC solutions
    with a minimal external component count and cost.
    The MIC2169A 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 MIC2169A senses current across the high-side NChannel 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 MIC2169A is available in a 10-pin MSOP package, with
    a wide junction operating range of –40°C to +125°C.
