  1.5A Monolithic Buck-Boost DC/DC Converter with
  Up to 95% Efficiency Features 2.5V–15V Input and Output
  Voltage Ranges
  Richard Cook Multicell high capacity batteries are increasingly becoming
  commonplace in handheld devices and industrial
  instruments that receive their power from a variety of
  sources. To maximize battery run time and support the
  variety of power sources, voltage regulators in multipower
  source systems must be able to maintain a constant output
  voltage even as the input voltage source resides above,
  below or equal to the output. This can be accomplished
  using two separate power converters with two controller
  ICs. A better solution is to use a single buck-boost DC/DC
  converter, which offers a smaller, simpler and more efficient
  design, attributes critically important in handheld devices.
  The LTC3111 is a monolithic buckboost converter with input and output
  voltage ranges of 2.5V to 15V and an
  output current capability of 1.5A. It
  allows conversion from a variety of
  power sources such as single or multi
  Li-ion cells, lead acid batteries, capacitor banks, USB cables or wall adapters. architecture, effectively eliminating jitter
  and EMI that can occur when crossing the
  boundary between step-up and step-down …
