  Power Supply Works with FET Drivers, DrMOS and Power
  Blocks for Flexible Placement Near Microprocessors
  Theo Phillips As microprocessors demand progressively more current at lower voltages, it becomes
  important to minimize conduction losses by placing the power supply as close to
  the load as possible. This increases the value of every square millimeter of board
  space near the load—particularly when multiple power stages are used. It is also
  important to locate the DC/DC controller away from high current paths, which can
  be difficult when the MOSFET gate drivers are in the controller package, because the
  gate traces must also be kept short. Sometimes the best solution is to use external
  power train devices or discrete N-channel MOSFETs and associated gate drivers.
  The LTC3860 is a dual output step-down
  DC/DC controller designed to work in
  conjunction with drivers or power train
  devices such as DrMOS and power blocks,
  enabling flexible design configurations
  with PolyPhaseВ® operation. Up to 12
  stages can be paralleled to increase output
  current and clocked out of phase to minimize input and output filtering (FigureВ 1).
  In PolyPhase configurations, both output voltage (VOUT) and ground terminals
  are monitored using a single differential
  amplifier, enabling tight regulation even
  where IR losses occur through vias, trace
  runs and interconnects. Regulation is …
