  Wide Input Voltage Range Boost/Inverting/SEPIC Controller
  Works Down to an Input Voltage of 1.6V
  Design Note 500
  Zhongming Ye
  Introduction
  Many of today’s electronic devices require an inverting
  or noninverting converter or sometimes both. They also
  need to operate from a variety of power sources including USB, wall adapters, alkaline and lithium batteries.
  To produce various polarity outputs from variable input
  voltages, power supply designers often use a variety
  of regulator ICs, which makes for a long inventory list.
  The LTВ®3759 operates over an input voltage range from
  1.6V to 42V and controls either positive or negative
  outputs using the same feedback pin, thus shortening
  the inventory list and simplifying design. It also packs
  many popular features such as soft-start, adjustable
  frequency and synchronization into a small footprint.
  The LT3759 comes in a 5mm Г— 4mm 12-pin MSE package and can be used in multiple configurations such as
  boost, SEPIC, flyback and Cuk topologies.
