Monolithic Dual PWM Hybrid Controller
Powering AMD SVI Split-Plane and PVI
Uniplane Processors
The ISL6323 dual PWM controller delivers high efficiency
and tight regulation from two synchronous buck DC/DC
converters. The ISL6323 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 ISL6323 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 ISL6323 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.
