  DESIGN IDEAS 2-Phase Controller for High Current,
  High Step-Down Ratio Applications
  by Xiaoyong Zhang
  One of the biggest challenges in designing power supplies for high speed
  digital systems is achieving high stepdown ratios at high load currents, all
  while maintaining high efficiency and
  meeting stringent transient response
  and board space requirements. Designers can easily meet this challenge
  by using the LTC3709 dual phase,
  synchronous step-down switching
  regulator.
  The LTC3709 uses a constant ontime with phase locked loops (PLLs),
  valley current control architecture to
  deliver very low duty cycles and does
  not require an output current sense
  resistor. Figure 1 shows the LTC3709
  in a step down circuit that features fast
  transient response and high efficiency
  over wide load range. High Current
  and High Efficiency Power losses, and the resulting heat,
  are significant problems in high
  current systems, so power supplies
  must be as efп¬Ѓcient as possible. The …
