  New Charge Pumps Offer Low Input and Output Noise
  Design Note 243
  Sam Nork
  Charge pump (inductorless) DC/DC converters are
  quite popular in space-constrained applications where
  low to moderate load currents must be supplied. Such
  converters are available in small packages, operate
  with very low quiescent current and require minimal
  external components. However, noise generation is
  one undesirable characteristic of most charge pumps.
  Unwanted noise can create a variety of problems.
  Noise generated at the power input can interfere with
  RF transmission and reception in wireless applications.
  Noise at the output can couple onto sensitive circuits
  or even create audible noise. The new LTC В®3200 family
  of boost charge pumps employs a new architecture
  designed to minimize noise at the input and output to
  mitigate such unwanted behavior.
  Burst ModeВ® Operation vs Constant Frequency
  Most regulating charge pump DC/DC converters operate using a Burst Mode architecture. Such regulator
  architectures provide the lowest quiescent current,
  but generate the highest levels of both input and output noise. With Burst Mode parts, the charge pump
  switches are either delivering maximum current to …

  DESIGN IDEAS Charge Pump Powers White LEDs
  by Steven Martin
  Introduction
  Most of today’s portable equipment
  uses a liquid crystal display to convey
  information to its user. Until recently,
  those displays have been monochrome
  and have used a low voltage light
  emitting diode (LED) such as red or
  green for backlighting. With the advent
  of color liquid crystal displays, a white
  backlight source is needed. Recently,
  a revolution in LED technology has
  lead to the long-coveted white LED.
  However, white LEDs, which are
  actually blue LEDs with a special
  phosphor in the lens, operate at a
  considerably higher voltage than red
  or green LEDs. White LEDs can
  require anywhere from 3.5V to 3.9V
  to operate at 15mA. In battery powered systems, it’s impractical to drive
  the LEDs directly from the battery
  and still control the LED current. To …
