  MIC2169B
  500kHz PWM Synchronous Buck
  Control IC General Description Features The MIC2169B is a high-efficiency, simple to use 500kHz
  PWM synchronous buck control IC housed in small
  MSOP-10 and MSOP-10 ePad packages. The MIC2169B
  allows compact DC/DC solutions with a minimal external
  component count and cost. The device features highoutput driver capability to drive loads up to 30A.
  The MIC2169B 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 within the smallest possible
  printed circuit board space area.
  The MIC2169B 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 currentlimiting digital soft-start. The MIC2169B is identical to the
  MIC2169A with the exception that the MIC2169B supports
  pre-bias loads and has a lower impedance gate-drive
  circuit. Internal pre-bias circuit prevents output voltage
  drooping and excessive reverse inductor current when
  powering up with a pre-bias voltage at the output. ...
