Dual PWM Controller Powering AMD SVI Split-Plane
Processors
ISL6329
The ISL6329 dual PWM controller delivers high efficiency and
tight regulation from two synchronous buck DC/DC converters.
The ISL6329 supports power control of AMD processors, which
operate from a serial VID interface (SVI). The dual output
ISL6329 features a multiphase controller to support the Core
voltage (VDD) and a single phase controller to power the
Northbridge (VDDNB).
A precision core voltage regulation system is provided by a
one-to-six-phase PWM voltage regulator (VR) controller. The
integration of two power MOSFET drivers adds flexibility in layout
and reduces 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 Northbridge portion of the processor. This
monolithic, dual controller with integrated driver solution
provides a cost and space saving power management solution.
For applications that benefit from load line programming to reduce
bulk output capacitors, the ISL6329 features temperature
compensated 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 ISL6329 supports Power Savings Mode by dropping the
number of phases to one or two when the PSI_L bit is set. For
even greater power efficiency, diode emulation and gate voltage
optimization are implemented in PSI mode.
