  L DESIGN FEATURES Power Management IC with
  Pushbutton Control Generates Six
  Voltage Rails from USB or 2 AA Cells
  Via Low Loss PowerPath Topology
  by John Canfield Introduction
  As the complexity of portable electronic
  devices continues to increase, the demands placed on power supplies, and
  their designers, expand dramatically.
  Not only must typical power systems
  accommodate multiple input sources,
  with voltages as low as 1.8V for two
  AA cells, but they must also provide
  an increasing number of independent
  output rails to support a wide range
  of requirements—for memory, microprocessors, backlights, audio and RF
  components. To further complicate
  matters, expanding feature sets add up
  to increased power dissipation, making
  it important to optimize overall power
  system efficiency. This is particularly
  challenging given that the constant
  drive to minimize the required board
  area and profile height of the power …
