  DESIGN IDEAS Efficient, Flexible Boost Converter Fits
  into Charge-Pump Footprint by Eddy Wells
  Introduction Handheld devices often use low
  power step-up DC/DC converters to
  power displays, LEDs and I/O circuitry, or to charge alternate power
  sources. Capacitive charge-pumps
  or inductor-based boost converters
  are the two most common solutions
  to step-up conversion, and each has
  certain advantages and trade-offs. A
  charge-pump converter offers a simple,
  compact solution, but it has a limited
  range of VIN to VOUT ratios, such as 3.3V
  to 5V. A traditional boost converter
  offers more efficient operation and a
  greater range of step-up ratios, but
  boost solutions typically take more
  space, and systems issues such as
  inrush current and short circuit protection are often solved with added
  external circuitry.
  The LTC3459 is a small, synchronous boost converter that addresses
  many issues found in a traditional
  boost converter. The LTC3459 offers Burst Mode operation for high …
