  DESIGN IDEAS 3-Phase Buck Controller
  for Intel VRM9/VRM10 with
  Active Voltage Positioning
  Introduction Accurate Load Line Control Each new generation of CPUs demands
  more from power supplies than the
  last: more power, tighter voltage regulation and faster transient response.
  Meeting all of the new requirements is a
  difficult proposition, but the LTC3738
  helps power supply designers do just
  that. It is a 3-phase buck controller
  with active voltage positioning specifically designed for Intel VRM9 and
  VRM10 (Figure 1). crucial. The current mode architecture
  of the LTC3738 evenly distributes
  the load, and thus thermal stress,
  across the channels. This improves
  the thermal performance and reliability of the entire power solution.
  The LTC3738 also includes a thermal
  detector that generates a VR_HOTB
  warning signal when chip itself gets
  hot (around 120В°C) plus a self-protect
  thermal detector that shuts down the
  device when chip becomes extremely
  hot and endangers the safety of the …
