  design features 15V Buck-Boost Converters with Ultralow 1.3ВµA Quiescent
  Current are Tailored to Micropower Applications and the
  Internet of Things
  Dave Salerno The proliferation of wireless sensors supporting the “Internet of Things” has increased
  the need for small, efficient power converters tailored to untethered low power devices.
  The new LTC3129 and LTC3129-1 are designed to satisfy this need. The LTC3129
  and LTC3129-1 are monolithic buck-boost DC/DC converters with an input voltage
  range of 2.42V to 15V. The LTC3129 has an output voltage range of 1.4V to 15.75V,
  while the LTC3129-1 offers eight pin-selectable fixed output voltages between 1.8V
  and 15V. Both parts can supply a minimum output current of 200mA in buck mode.
  Low power sensors can take advantage
  the LTC3129’s and LTC3129-1’s zero current
  when disabled (on both VIN and VOUT),
  and a quiescent current on VIN of just
  1.3Вµ A when power saving Burst ModeВ®
  operation is selected, making them ideal
  for Вµ Power and energy harvesting applications, where high efficiency at extremely
  light loads is crucial. Their buck-boost
  architecture makes them well suited
  to a wide variety of power sources. PWM mode, an accurate RUN pin threshold to allow the UVLO threshold to be
  programmed, a power good output and
  an MPPC (maximum power point control)
  function for optimizing power transfer …
