  Switching USB Power Manager with PowerPath Control Offers
  Fastest Charge Time with Lowest Heat – Design Note 415
  Dave Simmons
  Introduction
  Lithium-Ion and Lithium Polymer batteries are common
  in portable consumer products because of their relatively
  high energy density—they provide more capacity than
  other available chemistries within given size and weight
  constraints. USB battery charging is also becoming
  commonplace, as many portable devices require frequent
  interfacing with a PC for data transfer.
  As portable products become more complex, the need for
  higher capacity batteries increases, with a corresponding
  need for more advanced battery chargers. Larger batteries
  require either higher charging current or additional time
  to charge to their full capacity. Most consumers look for
  shorter charge times, so increasing the charge current
  seems obviously preferable, but increasing charge current
  presents two major problems. First, with a linear charger,
  increased current creates additional power dissipation
  (i.e., heat). Second, the charger must limit the current
  drawn from the 5V USB bus to either 100mA (500mW)
  or 500mA (2.5W) depending on the mode that the host …
