Monolithic Dual PWM Hybrid Controller
Powering AMD SVI Split-Plane and PVI
Uniplane Processors
The ISL6324A dual PWM controller delivers high efficiency
and tight regulation from two synchronous buck DC/DC
converters. The ISL6324A 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 ISL6324A features a multi-phase controller to support
uniplane VDD core voltage and a single phase controller to
power the Northbridge (VDDNB) in SVI mode. Only the
multi-phase 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 multi-
phase 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 ISL6324A features output
voltage droop. The multi-phase 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 ISL6324A supports Power Savings Mode by dropping
phases when the PSI_L bit is set. The number of phases
that the ISL6324A will drop to is programmable through an

The ISL6324A I 2 C interface also allows independent
programmable output voltage offset for both the Core and
North Bridge regulators. The I 2 C interface can also be used
to set the PGOOD and OVP trip levels for both regulators as
well.

NOTE: These Intersil Pb-free plastic packaged products employ
special Pb-free material sets, molding compounds/die attach materials,
and 100% matte tin plate plus anneal (e3 termination finish, which is
RoHS compliant and compatible with both SnPb and Pb-free soldering
operations). Intersil Pb-free products are MSL classified at Pb-free peak
reflow temperatures that meet or exceed the Pb-free requirements of
IPC/JEDEC J STD-020.
