  L DESIGN IDEAS USB Power Manager with
  High Voltage 2A Bat-Track
  Buck Regulator by Nancy Sun Introduction
  Personal navigation devices, HDDbased media players, automotive
  accessories, and other handheld products draw on an array of power sources
  for recharging their batteries. These
  sources include USB (nominally 5V),
  low voltage wall adapters (4.5-5.5V),
  high voltage wall adapters (12V–24V),
  FireWire (8V–33V) and automotive
  batteries (nominally 12V). The large
  supply of available sources leads to an
  increasing need for handheld devices
  that can accept a wide range of multiple
  input voltages without the need for
  myriad external power adapters.
  The LTC4090 is designed to accommodate both USB and high voltage
  sources by integrating a high voltage
  2A switching buck regulator, a USB
  input, a PowerPathв„ў controller and a
  linear battery charger into a compact,
  thermally enhanced 3mm Г— 6mm
