advertisement High Performance 3-Phase Power Supply Delivers 65A and
High Efficiency Over the Entire Load Range вЂ“ Design Note 312
Wei Chen
Introduction
CPUs used in notebook computers and other mobile
applications now draw more than 30A of current and
may draw as much as 65A in the near future. For
these heavy loads, high efп¬Ѓciency power supplies are
required to protect the system from excessive thermal
stress. With this in mind, PolyPhaseВ® switching DC/DC
converters have become the standard for CPU power
supplies because they are extremely efп¬Ѓcient at these
heavy loads. Nevertheless, for portable applications that
spend much of the time in sleep or standby modes, light
load efп¬Ѓciency has also grown in importance, where
conserving energy for maximum battery run-time is
also a priority. Unfortunately, traditional PolyPhase
converters, although exceptional performers at heavy
loads, do not yield comparable efп¬Ѓciencies at light load.
Linear Technology Corporation offers a solution to this problem with a new family of PolyPhase controllers that
allow the design of converters that are efп¬Ѓcient over
the entire CPU load range.
These new 3-phase controllers, the LTCВ®3730, LTC3731 …

DESIGN FEATURES High Performance 3-Phase Power
Supplies Yields High Efficiency over
the Entire CPU Load Range
by Wei Chen and Steve Hobrecht Introduction
VIN Thermal stress is a major concern for
enterprise CPUs that frequently draw
up to 100A of load current. PolyPhaseВ®
switching DC/DC converters reduce
thermal stress by providing high efficiency at heavy loads, and thus have
become the standard power supply
solution for high powered CPUs.
PolyPhase switchers are also finding
their way into mobile applications
where CPUs are drawing currents
greater than 30A, and will draw 65A
in the near future. Mobile CPUs pose
an additional problem, though. They
spend much of the time in sleep or
standby modes, meaning that light
load efficiency is important to maximize battery run-time. Traditional
PolyPhase converters, despite their
exceptional performance at heavy load,
are not as efficient at light load. …
