The ISL6324 dual PWM controller delivers high efficiency
and tight regulation from two synchronous buck DC/DC
converters. The ISL6324 supports hybrid power control of
AMD processors which operate from either a 6-bit parallel
VID interface (PVI) or a serial VID interface (SVI). The dual
output ISL6324 features a multiphase controller to support
uniplane VDD core voltage and a single phase controller to
power the Northbridge (VDDNB) in SVI mode. Only the
multiphase controller is active in PVI mode to support
uniplane VDD only processors.
A precision uniplane core voltage regulation system is provided
by a 2- to 4-phase PWM voltage regulator (VR) controller. The
integration of two power MOSFET drivers, adding flexibility in
layout, reduce the number of external components in the
multiphase section. A single phase PWM controller with
integrated driver provides a second precision voltage regulation
system for the North Bridge portion of the processor. This
monolithic, dual controller with integrated driver solution
provides a cost and space saving power management solution.
