  L DESIGN IDEAS Complete 3-Rail Power Supply in a
  4mm Г— 4mm QFN Package by John Canfield
  Introduction
  Battery-powered portable electronic
  devices such as portable media players, handheld PCs, and GPS receivers
  typically require several internal
  power supply rails: a 3.0V or 3.3V
  supply for audio, motor drivers, and
  micro hard disk drives; a 1.2V or 1.5V
  rail for a logic core; and often a 1.8V
  supply to support Flash memory. For
  devices supplied by a Li-Ion battery,
  the power system is further complicated by the fact that the 3.0/3.3V
  output rail lies within the discharge
  voltage range of the battery, thereby
  mandating a power supply solution
  that can step the input voltage up or
  down depending on the battery's state
  of charge. In addition, most systems
  require specific power-up sequencing
  between the multiple output voltage
  rails to ensure consistent and reliable
  system initialization. …
