  Current Mode Switching Supply with Ultralow Inductor DCR
  Sensing for High Efficiency and High Reliability
  Jian Li, Haoran Wu and Gina Le Current mode switching supplies have several advantages over voltage-mode switching
  supplies: (1) high reliability with fast, cycle-by-cycle current sensing and protection;
  (2) simple and reliable loop compensation—stable with all ceramic output capacitors;
  (3) easy and accurate current sharing in high current PolyPhase supplies. In high
  current applications, power losses in the current sensing component are a concern,
  so the resistance of the sense component must be as low as possible. The problem
  is that low resistance sensing elements produce reduced signal-to-noise ratios, such
  that switching jitter becomes an issue in high current, high density applications.
  The LTC3866 solves this problem by making it possible to build reliable current
  mode switching supplies with …
