  Introduction
  Everyone wants more power in less space. However, the
  task of designing a power supply is easy to describe but
  difficult to execute. How does a designer select an optimal
  set of components that yields the best possible power
  supply in terms of size, cost and performance? Well, it
  is easier if the selection is reduced to only a handful of
  components. A Small, Simple Solution
  The LT3681 integrates a wide input voltage range, high
  performance buck controller, power switch, high side
  bootstrapping boost diode and a power Schottky diode.
  All of these attributes are crammed into a tiny but thermally efficient 14-pin 3mm × 4mm DFN package. So,
  all a designer needs to implement a full-featured buck
  converter is to add the output LC п¬Ѓlter and a few passives. For instance, the LTВ®3681 reduces parts selection to only
  a few passive components by integrating all of the power
  semiconductors necessary to make a buck converter
  into a single package. Don’t think that this high level of
  integration limits the usefulness of this part. The LT3681
  accepts inputs from 3.6V to 34V, provides excellent line
  and load regulation and dynamic response, and offers …
