  L DESIGN IDEAS 500mA Output Current Low Noise
  by Yang Wen
  Dual Mode Charge Pump
  Introduction
  Charge pump (inductorless) DC/DC
  converters are popular in spaceconstrained applications with low to
  moderate load current (10mA–500mA)
  requirements. The devices in the
  LTC3203 family are low noise, high
  efficiency regulating charge pumps
  that can supply up to 500mA of
  output current from a single 2.7V
  to 5.5V supply. The LTC3203-1 and
  LTC3203B-1 produce a selectable п¬Ѓxed
  4.5V or 5V output. The LTC3203B
  produces an adjustable output voltage.
  The LTC3203-1 features automatic
  Burst Mode operation at light load to
  achieve low supply current whereas
  the LTC3203B and LTC3203B-1 operate at constant frequency to minimize
  both input and output noise. High
  switching frequency (1MHz) makes it
  possible to use only four tiny low cost …
