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
difп¬Ѓcult proposition, but the LTC3738
helps power supply designers do just
that. It is a 3-phase buck controller
with active voltage positioning speciп¬Ѓcally 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 …
