  DESIGN FEATURES L Charge Li-Ion Batteries Directly
  from High Voltage Automotive and
  Industrial Supplies Using Standalone
  Charger in a 3mm Г— 3mm DFN
  by Jay Celani Introduction
  Growth of the portable electronics
  market is in no small part due to the
  continued evolution of battery capacities. For many portable devices,
  rechargeable Li-Ion batteries are the
  power source of choice because of their
  high energy density, light weight, low
  internal resistance, and fast charge
  times. Charging these batteries safely
  and efficiently, however, requires
  a relatively sophisticated charging
  system.
  One additional problem faced by
  battery charger designers is how to deal
  with relatively high voltage sources,
  such as those found in industrial
  and automotive applications. In these
  environments, system supply voltages exceed the input ranges of most
  charger ICs, so a DC/DC step-down …
