  DESIGN FEATURES 30V, Dual Output Regulator Controller
  is Efficient, Rich in Features,
  and Saves Space by Teo Yang Long and Theo Phillips
  Introduction
  The LTC3802 is designed to excel in
  generating low output voltages from
  high input voltages, a common problem for the power supplies of fast CPUs.
  It is the latest in Linear Technology’s
  family of high speed, voltage feedback,
  synchronous step-down regulator
  controllers. It retains the constant
  frequency architecture and Burst
  ModeВ® operation of the LTC1702A,
  while improving on its performance
  and adding features (see Table 1).
  The input supply operating range
  is extended from a nominal 5V to the
  entire 3V–30V range. The internal
  reference voltage has decreased, allowing the output to go as low as
  0.6V. An advanced modulation scheme
  facilitates these low duty cycles and
  fast switching frequencies. The two
  channels are still run 180В° out of …
