Monolithic Dual PWM Hybrid Controller
Powering AMD SVI Split-Plane and PVI
Uniplane Processors
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.
For applications which benefit from load line programming to
reduce bulk output capacitors, the ISL6324 features output
voltage droop. The multiphase portion also includes advanced
control loop features for optimal transient response to load
application and removal. One of these features is highly
accurate, fully differential, continuous DCR current sensing for
load line programming and channel current-balance. Dual
edge modulation is another unique feature, allowing for
quicker initial response to high di/dt load transients. The
ISL6324 incorporates an I 2 C bus? that allows independent
programmable output voltage offset for both Core and
Northbridge. The I 2 C bus can also be used to set the
PGOOD and OVP levels.
