  DESIGN IDEAS L Step-Up/Step-Down Charge Pump
  DC/DC Converter Provides up to
  150mA in a Tiny 2mm Г— 2mm
  DFN Package
  by Julian Zhu
  Introduction
  A wide variety of handheld and portable
  applications are powered by Li-Ion
  batteries or AA cells. The wide input
  voltage range of a single Li-Ion battery
  (2.7V–4.2V) or 2 AA cells (1.8V–3.0V)
  requires a DC/DC converter that can
  step-up or step-down the input voltage
  to provide a п¬Ѓxed output voltage such
  as 3.3V or 2.5V. The new LTC3240
  step-up/step-down DC/DC converter
  is ideally suited for such applications
  and can provide up to 150mA in a tiny
  6-lead 2mm Г— 2mm DFN package.
  For input voltages greater than
  the regulated output voltage the
  LTC3240 operates as a low dropout
  regulator. When the input voltage …
