  design features 3A Output, 96% Efficient Buck-Boost DC/DC Converter
  Sets the Standard for Power Density and Noise Performance
  Richard Cook High power density has become a primary requirement
  for DC/DC converters, as they must keep up with ever
  increasing functional density of electronics. Likewise, power
  dissipation is a major concern for today’s functionally rich,
  tightly packed devices pushing the need for highly efficient
  solutions to minimize temperature rise. For applications
  where the input voltage source can be above or below
  the regulated output voltage, finding an efficient compact
  solution can be a challenge, especially at elevated power
  levels. Conventional design approaches, such as using
  a dual inductor SEPIC converter, produce relatively
  low efficiencies and relatively large solution sizes.
  The LTC3113 single inductor buck-boost
  converter offers a compact, highly efficient alternative. Internal low resistance
  switches allow the converter to support
  an impressive 3A of load current in a tiny
  4mm Г— 5mm package. The LTC3113 offers
  an extended input and output operating voltage range from 1.8V to 5.5V, with
  peak efficiencies reaching 96%. The
  internal PWM controller is designed for
  low noise performance and offers a seamless transition between buck and boost …
