  18V Buck-Boost Converter with Intelligent PowerPath
  Control Delivers >2A at 95% Efficiency from Dual Inputs
  Eddy Wells The requirement to operate from multiple input sources is
  increasingly common for applications powered from various
  battery chemistries, wall adapters and DC voltage rails
  such as USB. The ability to provide step-up or step-down
  conversion is often necessary, depending on the voltage
  range of each input and the desired output voltage.
  While powering from multiple sources
  is conceptually straightforward, implementation can be complicated. Losses
  in the power path, prioritization of the
  input sources and voltage spikes resulting
  from inductive cable insertion can all
  add cost and complexity to the system. with the ability to deliver over 2A current
  to the load. The LTC3118’s current mode
  control architecture responds rapidly to
  line or load transients, maintaining tight
  regulation of the output. For battery
  powered applications, extended run times
  are achieved with Burst ModeВ® operation. The LTC3118 addresses these issues by
  combining a dual, low loss PowerPath
  controller with a high efficiency buckboost converter, as shown in Figure 1. The
  unique architecture allows conversion …
