  DESIGN IDEAS L 94% Efficient, Low Noise, Step-Up
  DC/DC Converter in 2mm Г— 2mm
  DFN Package Offers Unrivaled
  Performance and Solution Size
  by Bert Hepfinger Introduction
  As handheld electronic devices shrink,
  the need for compact, high efficiency
  power converter solutions grows. The
  new LTC3427 is a full featured, low
  noise, step-up converter that is ideal
  for space constrained applications. It
  integrates a fixed frequency, internally
  compensated, synchronous boost converter with output disconnect, inrush
  current limiting and soft start into a
  low profile 0.75mm Г— 2mm Г— 2mm
  DFN package. A switching frequency
  of 1.25MHz minimizes the solution
  footprint by allowing the use of tiny,
  low profile inductors and ceramic
  capacitors. The LTC3427’s fixed frequency operation makes it ideal for
  noise sensitive applications where the
  wide frequency spectrum associated
  with multiple mode converters may …
