  Seamless, Automatic Transition Between Two Input Power
  Sources and Meets Stringent CISPR 25 Class 5 EMI Limits
  John Canfield Many electronic devices must seamlessly transition
  between a wide variety of input power sources—such as
  batteries, automotive rails, wall adapters and USB ports.
  Traditionally, power supply designers rely on Schottky
  diodes or a prioritized PowerPath (IC controlled MOSFET
  switches) to combine input sources. Since both methods
  require additional components in front of the switching
  power supply, solution size and design complexity increase
  while overall supply efficiency is reduced. With its ability to
  operate directly from two different input power sources,
  the LTC3126 eliminates these disadvantages and enables
  smaller and higher efficiency multisource power supplies.

  PEAK RADIATED EMI (dBВµV/m) The LTC3126 operates directly from two
  independent power sources, drastically
  simplifying the design of such systems
  by minimizing component count and
  solution size, as shown in FigureВ 1,
  while maintaining high overall system
  efficiency. Ease of use is enhanced by …
