  DESIGN IDEAS L High Efficiency, Low Input Voltage,
  Synchronous Buck Controller Drives
  by Joseph Duncan
  up to 15A Load Current
  Introduction IPRG The LTC3822 is a synchronous stepdown DC/DC converter that drives
  external N-channel power MOSFETs
  to maximize average current drive for
  the lowest cost. Its No RSENSE constant
  frequency architecture minimizes the
  number of external components, and
  a programmable frequency of up to
  750kHz allows the use of small surface-mount inductors and capacitors.
  This DC/DC controller is optimized
  for 3.3VIN and Lithium-Ion applications allowing VOUT as low as 0.6V
  while maintaining 1% precision. The
  all N-channel MOSFET drive simplifies component selection as well as
  drastically increasing the current
  capabilities of a typical circuit. Even
  with 3.3V gate drive, the LTC3822 is
  capable of controlling more than 15A
  load current while maintaining high
  efficiency. RUN ITH LTC3822 SW GND 59k GND VOUT
