DATASHEET

ISL6323B

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.
