  DESIGN IDEAS Inductorless, Efficient Step-Down
  DC/DC Converter Provides Dual
  Low Noise Outputs in Spaceby Bill Walter
  Constrained Designs
  Introduction Increase Battery Run Time Linear Technology’s new LTC3252
  switched capacitor step-down DC/
  DC converter squeezes dual adjustable outputs into a space saving 3mm
  by 4mm DFN package. Each output is
  programmable within a range of 0.9V
  to 1.6V, is capable of 250mA of current, and operates from a single 2.7V
  to 5.5V supply. To keep the converter
  footprint small, the LTC3252 operates
  at high frequency, allowing the use of
  tiny low cost ceramic capacitors—no
  inductors are required. The LTC3252 also features Burst
  ModeВ® operation, which allows the
  LTC3252 to achieve high efficiency
  even with lightly loaded outputs. While
  in Burst Mode operation the LTC3252
  delivers a minimum amount of charge
  for a few cycles then goes into a low
  current state until the output drops
  enough to require another burst of …
