Monolithic Dual PWM Hybrid Controller
Powering AMD SVI Split-Plane and PVI
Uniplane Processors
The ISL6323B dual PWM controller delivers high efficiency
and tight regulation from two synchronous buck DC/DC
converters. The ISL6323B 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 ISL6323B 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 two-to-four-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 ISL6323B features output
voltage droop. The multi-phase portion also includes
advanced control loop features for optimal transient
response to load apply 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 ISL6323B supports Power Savings Mode by dropping
the number of phases to two when the PSI_L bit is set.
